Barium zirconate titanate (BZT) is considered to be an important dielectric material for the fabrication of multilayer ceramic capacitors (MLCCs). The synthesis of nanocrystalline powders of high purity is the key to improving the performance of BZT-based ceramics. In this study, we developed Ba(Zr0.15Ti0.85)O3 nano powders with a perovskite structure and a homogeneous granularity through the oxalate precipitation method. The average particle size of the powders can be controlled from 30 to 100 nm at different calcining temperatures. The sintering property of the powders is superior to that of powders prepared by the conventional solid-state method, such that the more compact ceramics with a smaller grain size can be obtained at a sintering temperature of 1250 °C. The dielectric property of the ferroelectric-powder-based ceramics was so excellent for the development of dielectric materials for base-metal electrode multilayer ceramic capacitors (BME MLCCs) with a large capacitance.
