  title={Study on the Function Variation of Co_2O_3 in ZnO Varistors},
  author={Meng Mei},
The effect of amount of metal oxide Co2O3 on the crystal growth electrical performance of ZnO varistors are evaluated. It is an analysis made on improvement of Co2O3 content to various performances of ZnO semiconductor,as well as the defect type which may occur.The test result indicates that with decrease of the content of Co2O3 within the range of 0.6%~0.2%, the average crystal size of the ZnO varistor decreases,the power frequency voltage withstand ability increases,and the non-linear factor… CONTINUE READING
