用sol-gel方法制备掺杂的ZnO纳米粉体分析讨论了这种粉体对材料显微结构,材料电学特性如非线性系数,压敏电压和介电特性的影响。与传统方法制成的粉体相比,sol-gel方法制成的纳米粉体具有掺杂均匀,晶粒尺寸分布均匀,其电学特性得到较大提高。

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 inv
