| 摘 要： | 本文研究了Ｎｂ＿２Ｏ＿５掺杂以及Ｎｂ＿２Ｏ＿５与ＺｎＯ煅烧对ＺｎＯ压敏电阻器电性能的影响。实验表明，Ｎｂ＿２Ｏ＿５的掺入使压敏电场减少，当Ｎｂ＿２Ｏ＿５含量为０．１％ｍｏｌ时，其压敏电场最小．非线性系数最大。煅烧温度越高，压敏电场越高，非线性系数越大。

| Abstract: | This paper presents the effects of Nb_2O_5 dopant and calcination on electrical characteristics of ZnO varistors.The experiments show that the breakdown electrical field and nonlinear coefficient reach the maximum values at the amount of 0.1%mol of Nb_2O_5.The higher the calcination temperature,the higher the breakdown electrical field and nonlinear coefficient are. |
