Abstract Scope |
Cold Sintering has provided new processing strategies for tuning the microstructure and electrical properties of dielectrics. The thermal stability and performance of these materials can be improved by broadening the relative permittivity and shifting the Curie temperature. Previous studies have achieved this in barium titanate systems by incorporating curie shifters such as strontium onto the A lattice site during CSP via flux chemistry. To facilitate further optimization of electrical properties alternative methods of incorporating dopants into the material will be explored. Size effect phenomenon provides another path towards control over the tetragonal to cubic phase transition. This study will also systematically investigate the impact of size effects on cold sintered barium titanate systems. Ultimately this work seeks to provide a deeper insight into fundamental sintering behavior during CSP which in turn allows for new paths to material design. |
