| 摘 要： | 研究了MnCO3,CuO对0.90(Sr0.54Pb0.26Ca0.20)TiO3-0.1Bi2O3·3.5TiO2为系统的中高压瓷介电容瓷料的介电性能的影响,实验发现掺加MnCO3能提高居里温度,使ε-t峰向正温方向移动.MnCO3能起压峰作用,使介电常数(ε)减小,同时能改善瓷料的温度性能.MnCO3可以降低瓷料的低温损耗,但室温损耗变化不大.CuO的掺加有明显的展宽作用.

| Abstract: | The influence of MnCO3, CuO on the dielectric behaviors of the system 0.9(Sr0.54Pb0.26Ca0.20)TiO3- 0.10Bi2O3.3.5TiO2 was investigated. The results show that the permittivity peaks decrease and shift to a high temperature with the additon of MnCO3, and the incorporation of CuO can broaden the permitivity peak, leading to a low temperature coefficient of permittivity. |
