| Abstract: | A sol-gel method for the preparetion of doped ZnO varistor nanometer powders was described.The influence of the ZnO nanometer powders on the microstrue, the nonlinear parameter,the breakdown voltage, and the dielectric properties of ZnO varistor was investigated. Compared to the conventional mixed oxide technique, varistor ceramics made from sol-gel powders with a more homogeneous distribution of dopants, a regular microstructure and show improvement electrical properties. |
