主要研究了Pr掺杂对 Zn-Bi 系压敏电阻的性能的影响。当Pr6 O11掺杂量为5.49%(质量分数)，烧成温度为1150℃时，压敏电压达到400 V/mm；当Pr6 O11掺杂量为3.37%(质量分数)，烧成温度为1200℃时，非线性系数达到48。研究还发现 Pr-Y 共掺杂能显著地提高 Zn-Bi 系压敏电阻的压敏电压，但会对体系的非线性系数和漏电流产生不利影响。

In this article,we mainly studied the effects of Pr doping Zn-Bi system on its properties.The results show that when the sintering temperature was 1150 ℃ and the dopant of Pr6 O11 was 5.49wt%,the varistor voltage got 400 V/mm;and when the temperature was 1200 ℃ and 3.37wt% Pr6 O11 doping,the nonlinear co-efficient got 48.Study also find that the co-doping of Pr-Y can significantly improve the varistor voltage of Zn-Bi system,but it has the adverse effects on the nonlinear coefficient and leakage current.
