【Abstract】 The cold-pressing ceramic processing technique was used to prepare high-permittivity Barium Titanate ceramics. XRD, SEM, temperature and frequency dependence of dielectric constant, and hysteresis loop were measured to investigate and study structure, microstructure, dielectric and ferroelectric properties of Barium Titanate dielectric ceramics. This work lay an experimental foundation for the application of monolithic highly dielectric capacitor materials.更多还原
