  • Electrospun Chitosan/Silver Doped-Hydroxyapatite Nano-Fibers on Thermal
           Conductivity Modified Si3N4 Ceramics with Different Sintering Cooling Rate

    • Abstract: Publication date:  Jun 2021
      Source:Universal Journal of Materials Science  Volume  9  Number  1  Mevlüt Gürbüz   and Pınar Uyan   Dental implants are exposed to cycle loadings and thermal changes. The thermal properties of the materials in dentistry are important in terms of the biological changes that these materials will create in living tissues. The normal temperature of the oral cavity varies between 32-37℃, while eating, it can vary between 0-80℃ with hot-cold foods which led to the trauma and implant deteriorations. Si3N4 ceramic is a good candidate to solve these problems due to its inertness, high fracture toughness, strength, high thermal shock resistance and low density. Also, the surface modification of Si3N4 is important to enhance the interaction between the implant and bone. In recent years, biodegradable organic biomaterials as CTs (CTs) and silver doped hydroxyapatite (HAPs) combinations have a great attention to improve the Si3N4 effectiveness. In this study, MgO, SiO2, and Y2O3 included substrates were fabricated for fast and slow cooling rate during sintering in dental applications. CTs/HAPs fibers were coated with the electrospinning method to develop a modified Si3N4 substrate. The crystal structure, microstructure and thermal diffusivity measurement of the substrates and spun surfaces were characterized with XRD, SEM and Laser Flash Method. From the results, the higher density (3.25g/cm3) and thermal conductivity (46.35W/mK) for Si3N4 were observed for the fast cooling process during sintering compared with the slow cooling process (3.22g/cm3 and 44.60 W/mK). The hardness and strength of the fast cooled substrate were measured as 1350 HV and 1800 MPa which are greater than the slowly cooled samples (1190 HV, 1670 MPa). CTs /HAPs fibers are homogeneously deposited with electrospinning on the surface of the fast cooled Si3N4 substrate to develop the surface functionality. This functionalized substrate can be a candidate in dental applications.

  • Fabrication and Characterization of Li2CO3 Modified Low Temperature
           Sintered PZT-5H Compositions for Multilayer Piezoelectric Ceramics

    • Abstract: Publication date:  Dec 2021
      Source:Universal Journal of Materials Science  Volume  9  Number  2  Mert Gül   Ayşe Gül Toktaş   Hakan Güleç   Mevlüt Gürbüz   and Aydın Doğan   In the use of piezocermic applications, piezoceramic compositions have high d33 (>500 pC/N) and Kt (2000) such as PZT-5H. However, these ceramics can be sintered at high temperatures up to 1200˚C). Since these require the use of Ag-Pd inner electrodes with higher Pd ratio, multilayer ceramics are not preferred due to their high costs. In this study, it was aimed to reduce the sintering temperature without dramatically losing the electrical properties of the PZT-5H ceramics with high d33, kp and dielectric constant values. In this context, the PZT-5H composition was modified with different proportions of Li2CO3 and sintered for 2-4 hours at different sintering temperatures such as 875˚C-1250˚C depending on the ratio of additions. The piezoelectric and ferroelectric properties of the ceramics were investigated and obtained values were compared with undoped PZT-5H. It was observed that the d33 values of the different amount of Li2CO3 added compositions sintered at optimum sintering temperature are close that the composition without additives. In this way, it is predicted that 9/1 Ag/Pd and Ag inner electrode materials can be used in multilayer production and their costs can be reduced.
