Y/Ce共掺杂对高梯度压敏陶瓷电阻综合电性能的改善

Dianci bileiqi
对ZnO基压敏电阻进行了Y、Ce两种元素的共掺杂，通过改变Y和Ce之间的比例，寻找最优的Y、Ce共掺杂比例。通过X射线衍射仪、扫描电镜对样品的微观结构进行表征，利用对数正态分布概率密度函数对晶粒粒径分布进行了拟合。利用金属氧化物直流参数测试仪对样品的压敏电压、漏电流和非线性系数进行测量，利用脉冲电流测试设备测试样品的8/20μs雷电波残压比与2ms方波电流通流能力。采用精密阻抗分析仪测试样品的C-V特性曲线。研究发现当Y、Ce两种元素协同作用时，能使ZnO晶粒尺寸分布最优化。当两种稀土离子的比例合适时 ...
