固溶体系列（1 x）BaTiO 3 Bi（Mg0.5Zr0.5）O3中的陶瓷在x < 0.05时为单相四方晶系，在x > 0.1时为立方晶系。相对介电常数（ε（r））对温度的曲线图显示x = 0.05时的双峰，对于x > 0.1的组合物，变为单一的频率依赖性峰。- r最大值随着x的增加而逐渐下降，导致在很宽的温度范围内接近温度稳定的介电性能。对于x >= 0.3，从20摄氏度到430摄氏度，tan δ = 570 +/-15%，
Ceramics in the solid solution series (1 x)BaTiO3 Bi(Mg0.5Zr0.5)O-3 are single-phase tetragonal for compositions x < 0.05, and cubic for x > 0.1. Plots of relative permittivity (epsilon(r)), versus temperature show double peaks for x = 0.05, changing to a single, frequency-dependent peak for compositions, x > 0.1. A progressive decline in - r max with increasing x leads to near temperature-stable dielectric properties over a wide temperature range. For x >= 0.3, epsilon(r) = 570 +/- 15%, from 20 degrees C to 430 degrees C, and tan delta
