  Adding trivalent transition metalions,reducing additives’ particle size and controlling the sintering schedule can significantly reduce the grain size,lower the porosity,increase the number of grain boundaries and enhance the grain boundary barrier,thus effectively improve the potential gradient of ZnO varistor.

  采用三价过渡金属离子掺杂、减小添加剂粉料颗粒粒度以及控制合理的烧成制度,能明显减小晶粒尺寸,降低气孔率,增加晶界数目,提高晶界势垒,从而有效提高ZnO压敏电阻片的电位梯度。
