  • Evaluation and Modeling of Scrap Utilization in the Steelmaking Process
    • Abstract: Abstract The study of scrap melting provides data for increasing the scrap utilization rate. Here, an evaluation model is established to analyze the effect of each factor on scrap melting using statistical methods for the first time. Subsequently, the quantitative relationship between the influencing factors and melting parameters is obtained. Back propagation (BP) neural networks and multiple regression are used for predictions. For scrap melting controlled by carbon mass transfer when the bath temperature range is 1573–1723 K, the relative contribution of each parameter was mixing power > bath temperature > specific surface area > carbon content. The predicted values of the BP neural network are more accurate than those of multiple regression. The relative errors of average melting rate, average mass melting speed, and mass transfer coefficient of training sets are 14.02%, 13.95%, and 7.19%, respectively, which decrease by 22.71%, 47.22%, and 69.46%, respectively, compared with those of the regression equations after outliers are removed.

  • Leaching of Antimony from Stibnite Ore in KOH Solution for Sodium
           Pyroantimonate Production: Systematic Optimization and Kinetic Study
    • Abstract: Abstract This work aims to shed light on the leaching kinetics of antimony from stibnite ore in potassium hydroxide (KOH) solution. Response surface methodology based on central composite design was used to investigate the effect of time, temperature, solid to liquid ratio (S/L), and KOH concentration as independent parameters on the leaching efficiency of antimony. According to the results, time shows the most significant effect on the leaching yield of antimony, followed by temperature. The optimum leaching condition was obtained at a KOH concentration of 0.5 mol/L, temperature of 25°C, S/L of 100 g/L, and time of 133 min, with an antimony leaching yield of 56.5%. Kinetic studies based on the shrinking core model illustrated that the diffusion process through the ash layer is the rate-limiting step, with an activation energy of 4.97 kJ mol−1. Finally, antimony was recovered from the leach liquor in the form of NaSb(OH)6. This study can pave the way for the development of new hydrometallurgical processes for antimony recovery from the sulfide minerals.

  • Observation of Fundamental Mechanisms in Compression-Induced Phase
           Transformations Using Ultrafast X-ray Diffraction
    • Abstract: Abstract As theoretically hypothesized for several decades in group IV transition metals, we have discovered a dynamically stabilized body-centered cubic (bcc) intermediate state in Zr under uniaxial loading at sub-nanosecond timescales. Under ultrafast shock wave compression, rather than the transformation from α-Zr to the more disordered hex-3 equilibrium ω-Zr phase, in its place we find the formation of a previously unobserved nonequilibrium bcc metastable intermediate. We probe the compression-induced phase transition pathway in zirconium using time-resolved sub-picosecond x-ray diffraction analysis at the Linac Coherent Light Source. We also present molecular dynamics simulations using a potential derived from first-principles methods which independently predict this intermediate phase under ultrafast shock conditions. In contrast with experiments on longer timescale (> 10 ns) where the phase diagram alone is an adequate predictor of the crystalline structure of a material, our recent study highlights the importance of metastability and time dependence in the kinetics of phase transformations.

  • Comparison of Biomass and Coal in the Recovery Process of silicon in an
           Electric Arc Furnace
    • Abstract: Abstract Silicon recovery of silica ore ( \( {\text{SiO}}_{2} \) ) has been studied with two types of carbon materials, charcoal as a biomass and coal as a fossil fuel, at elevated temperatures between 1800 and 2000°C in an electric arc furnace. The effects of porosity and electrical resistance of the carbon materials were investigated. To this end, recovery of silicon and ferrosilicon production were tested separately by charcoal and coal, and the products were investigated both qualitatively and quantitatively. A higher electrical resistance of charcoal was found in comparison with coal, with increased efficiency of the furnace and decreased electric energy consumption (per ton of product). The efficiency of the furnace using charcoal and coal was 92.13% and 77.4%, respectively. In addition, the higher porosity of charcoal facilitates the flow of SiO gas through the carbon material leading to a higher reactivity and reducing the electric energy consumption for each ton of FeSi.

  • Investigation of Microwave and Thermal Processing of Electrode Material of
           End-of-Life Ni-MH Battery
    • Abstract: Abstract Ni-metal hydride (NiMH) batteries should be recycled, as they contain base metals (Ni, Co) and rare earth elements (La, Ce). In this study, thermal and microwave treatments are investigated as a pre-treatment method for decomposing electrode material (Ni(OH)2 and LaNi5). The kinetic analysis of thermal decomposition electrode material yields the activation energy of 41.3 kJ/mol. The maximum percentage of lanthanum nickel oxide phase and cerium oxide phase is obtained at 1000°C of thermal treatment and 15 min of microwave exposure. The formation of melted balls of Ni and its oxide (Ni ~ 72.8%) was observed in microwave exposure, and the tendency of ball formation decreased with increasing exposure time. The effect of microwave exposure and thermal treatment on the acid leaching (1 M HCl, at S/L-1:20, at 70°C for 2 h) was studied. The leaching results showed NiO and CeO2 phases in the leach residue of thermal and microwave treated products.

  • Thermodynamics and Synthesis of Cu Powder from CuO in Waste Tire-Derived
           Pyrolytic Gas Atmosphere
    • Abstract: Abstract The present study aimed to investigate the reduction behavior of CuO particles under the gaseous atmosphere generated by waste tire pyrolysis. Thermodynamics of the reduction process indicated that CuO could be reduced to the metal via the tire (rubber) pyrolysis route in the temperature range 700–900 K. Oxide reduction experiments were conducted as a function of the reactant mass ratio (mtire/mCuO) and temperature (600–900 K). The extent of waste pyrolysis increased as the temperature was raised to 900 K. This was accompanied by an increase in the oxide reduction. A significant reduction was attained at mtire/mCuO = 1.28 when the reactants were heated to 800 K and 900 K. Adding a small amount of waste high-density polyethylene to the tire sufficed for full CuO reduction. CuO reduction reactions and morphological evolution of flower-type CuO particles to relatively equiaxed Cu particles were discussed in terms of experimental and theoretical findings.

  • Textured Polymer Surfaces Mimicking the Tactile Friction Between Wood and
           Skin
    • Abstract: Abstract Polymer-based furniture with wood-like visual printing is widely used in domestic and office applications. Although polymers could fulfil the high quality requirements of strength and appearance, they cannot mimic the feel of wood during touch. In this study, polymers with textured surfaces were designed to mimic the tactile friction and naturalness of wood. The influence of a series of factors on tactile friction was assessed. Textured polypropylene surfaces showed a 14.8% reduction in friction, and were more similar to wood compared to un-textured rough polypropylene surface, indicating the significant influence of surface texture on tactile friction. The touch perception test further proved that polymer samples were perceived as more natural with a rough or textured surface than with a smooth surface. This study suggests that, with a detailed design of the surface texture parameter, it is possible to mimic the tactile friction and naturalness of wood by using textured polymers.

  • Low-Temperature Molten Salt Synthesis and Characterization of
           Nanowire-Like TaB 2 Powder
    • Abstract: Abstract TaB2 nanopowder has been prepared by the molten salt synthesis (MSS) technique. Nanowire-like TaB2 nanopowder was successfully synthesized by reacting in the Ta2O5–MgB2 system using KCl/NaCl as reaction media. The impact of the firing temperature (800°C to 1000°C), firing time (1 h to 4 h), and ratio of reactants to salt (1:0, 1:2, 1:5, and 1:10) on the preparation of the TaB2 nanopowder was examined. The resultant powder samples were characterized by scanning electron microscopy (SEM), x-ray diffraction (XRD) analysis, transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and surface area analysis (SAA). The results showed that the reaction involved in the formation of crystalline TaB2 nanopowder could be completed successfully at 1000°C after 4 h of firing when the mass ratio of reactants to salt was 1:5. The resulting TaB2 nanopowders exhibited nanowire-like morphology.

  • Production Strategy for Manufacturing Large-Scale AlSi10Mg Components by
           Laser Powder Bed Fusion
    • Abstract: Abstract The long production time required for large-scale parts fabricated by laser powder bed fusion (LPBF) tends to induce cracks, distortions, and overheating problems. In this work, to address these challenges, we explored and established a suitable strategy for producing large AlSi10Mg components. The platform temperatures to prevent cracks and distortions were firstly determined. Then, the in situ aging behavior was investigated for samples under various platform temperatures and holding times. Our results revealed that platform temperatures of 150°C and 200°C can effectively prevent cracks and minimize distortions. Besides, using 150°C, samples can reach peak hardness with a holding time less than 13 h. In comparison, those samples produced with a holding time longer than 13 h at 150°C and 200°C show obvious over-aging responses and thus lower hardness. However, such a hardness impoverishment can be recovered by using a T6 post-process heat-treatment.

  • Recovery of Indium from Hard Zinc Slag by Pressure Leaching and Solvent
           Extraction
    • Abstract: Abstract In this study, hydrometallurgical processes involving pressure acid leaching and solvent extraction were developed to aid recovery of indium from zinc slag, which is produced in the imperial smelting process. Four different acid leaching methods were studied, namely atmospheric leaching, atmospheric leaching with KMnO4, roasting-atmospheric leaching, and oxygen pressure leaching in a sulfuric acid medium. Oxygen pressure acid leaching is the most effective method for indium extraction, and 94.1% of indium was leached under the optimum conditions, i.e., 300 g/L H2SO4,oxygen pressure 0.4 MPa, liquid/solid ratio 10 mL/g, and temperature 100°C for 5 h. X-ray diffraction and scanning electron microscopy examination of the raw material and leaching residue samples indicated that the intermetallic compounds Cu5Zn8and Cu2Zn, metallic zinc, and iron in the raw material dissolved, leaving the insoluble components PbSO4 and Pb as the major compounds in the leaching residue. A 98.5% proportion of the indium in the leaching solution was selectively extracted with 30% bis(2-ethylhexyl) phosphate and 70% kerosene by three-stage counter-current extraction, and 99.5% of the indium in the loaded organic phase was stripped by 6 mol/L HCl through four-stage counter-current stripping. The overall recovery yield of indium through all processes was approximately 92%.

  • Investigations on Positive (Sm 3+ ) and Negative (Ho 3+ ) Association
           Energy Ion Co-doped Cerium Oxide Solid Electrolytes for IT-SOFC
           Applications
    • Abstract: Abstract Novel compositions of positive (Sm3+) and negative (Ho3+) association energy ion co-doped cerium oxide solid electrolytes were synthesized and analyzed for intermediate-temperature solid oxide fuel cell (IT-SOFC) applications. Powder x-ray diffraction (XRD) and Raman studies confirmed the phase of pure cubic fluorite structure, while densely packed porous-structured morphology was affirmed with high-resolution scanning electron microscope (HR-SEM) micrographs. The formations of oxygen vacancies and association energies were analyzed through optical properties using ultraviolet (UV) and photoluminescence (PL) spectra. Thermal analysis revealed high thermal stability without any structural deformations and a high thermal expansion coefficient at the intermediate temperature range. The incorporation of Sm3+ ions acts as an oxygen vacancy generator which influences the ionic conductivity properties, and Ce0.8Sm0.1Ho0.1O2−δ solid electrolyte showed the high conductivity of 0.72 × 10−2 S/cm at 600°C specifying that this solid electrolyte might be an excellent candidate for IT-SOFC applications.
