Major factors affecting the dielectric properties and reliability of solid stated reacted BaTiO3 powders for capacitor.

In this study, solid-state BaTiO₃ was successfully synthesized after the disintegration of the starting materials (BaCO₃ and TiO₂) under various conditions. By analyzing the microstructure, tetragonality, crystallinity, and particle size distribution of the synthesized powder, the factors that affected the properties of the BaTiO₃ solid-state synthetic powder were successfully identified. Furthermore, the changes in the dielectric constants (temperature characteristic coefficients) of the sintered specimens were investigated using each powder, according to the dielectric characteristics, high-temperature resistance, and temperature, to identify the direct and indirect relationships between the disintegration conditions, synthetic powders, and sintered specimens. Finally, optimal conditions for the uniform solid-state synthesis of BaTiO₃ powder for multilayer ceramic capacitor production were derived. [ABSTRACT FROM AUTHOR]
