A is trivalent or bivalent cations and B is quadrivalent and quinquevalent cations). As a member of the pyrochlore family of compound, bismuth zinc niobate is a typical high frequency dielectrics with high permittivity and low dielectric loss, and can be applied as various devices, such as temperature-stable multilayer ceramics capacitor(MLC) and microwave resonator and filter. Bismuth zinc niobate system......
