摘要:

Bi4Ti3O12在低压氧化锌压敏电阻器的烧结过程中起着重要作用。通过使用扫描电子显微镜(SEM)研究了添加Bi4Ti3O12粉体的陶瓷烧结过程。结果表明,使用纳米Bi4Ti3O12粉体的压敏电阻所获得的电压梯度更低,Zn2TiO4相的形态和分布影响压敏电压的分散性。

关键词: 低压ZnO压敏电阻, Bi4Ti3O12, 晶粒长大

Abstract:

The Bi4Ti3O12 plays an important role in the process of sintering of the lowvoltage zinc oxide varistors.In this article,sintering of ceramic doped with Bi4Ti3O12 is studied by using SEM.The results show that varistors doped with nanometer Bi4Ti3O12 powder can obtain lower breakdown voltage,and the form and distribution of Zn2TiO4 phase affect the uniformity of breakdown voltage.

Key words: lowvoltage zinc oxide varistor;Bi4Ti3O12;grain growth
