摘要
通过使用高频等离子法制备纳米材料,研究纳米材料对氧化锌压敏电阻微观结构和电性能的影响。结果表明,烧结温度在1 080～1 120℃范围内可制备高性能的氧化锌压敏电阻陶瓷,其阀片的电位梯度达到429 V/mm,漏电流为6μA,非线性系数为39,能量吸收密度为296 J/cm3,性能远高于传统阀片。
Through the use of nanometer materials prepared by high frequency plasma method, the effect of nanometer zinc oxide varistor material on microstructure and electric properties was studied. The results show that in a wide range of sintering temperature, high performance zinc oxide varistor ceramics can be prepared. The potential gradient of valve plate is 429 V/mm, leakage current is 6 μA, and nonlinear coefficient is 39, absorbed energy density is 296 J/cm3. Performance is much higher than that of the traditional valve.
