| 摘 要： | 利用传统陶瓷制备工艺制备具有一定压敏特性的ZnO陶瓷材料，详细分析了Bi2O3掺杂对材料性能的影响及导致这一影响的具体原因，用MY3C-2型压敏电阻器三参数测试仪测试了样品的压敏电压，压比和漏流，并用BD-86型X射线衍射仪进行了物相分析，测试结果表明：在适合掺杂范围内，Bi2O3的增加有利于样品的非线性系数α及压敏电压的提高，且漏流IL随掺杂量的增加减小，超出这一范围后，样品的电学性能将会恶化，物相分析表明在添加Bi2O3，Sb2O3和BaCO3的ZnO陶瓷中，存在ZnO相，Bi2O3相，Zn223Sb0.67O4(尖晶石)相和BaSb2O6(偏锑酸钡)相。

| Abstract: | By adding Bi_2O_3,Sb_2O_3,BaCO_3 and SiO_2 into ZnO powder of high purity among the traditional compositions,ZnO varistor ceramics are made by traditional process.Influence of Bi_2O_3 contents on structure and properties of ZnO-based varistors has been studied systematically.The results show that the ZnO varis for properties are satisfactory when the amount of Bi_2O_3 is in a satisfactory range.The phases have been analysed by X-ray.There are four phases in ZnO varistor,including ZnO phase,Bi_2O_3 phase,Zn(2.23) Sb(0.67)O_4 phase and BaSb_2O_6 phase. |
