掺杂对低压ZnO压敏陶瓷材料显微结构及性能的影响(3)

Effect of Doping on Microstructure and Electrical Properties of low voltage ZnO Varistors (3)

本文探讨了多种金属氧化物对ZnO—Bi_2O_3—TiO_2系材料的改性作用和对其微结构的影响,为得到预定性能的材料提供了掺杂方面的试验依据。

Ceramic Varistors in ZnO-Bi2O3-TiO2 system containing Co2O3. MnO2, Ni2O3, Cr2O5 were prepered and the effect of these additives on the electrical properties and microstructure of the specimens was investigated. It may provides abandant experimental basis for getting predetermine varis-tors.
