Effect of TiO_2 Forms on the Microstructure and Property of Low-voltage ZnO Varistor

2005 
Purpose of the research for low-voltage ZnO varistor was introduced briefly. Efficiency of TiO_2 in different forms (including micrometer powder, nanometer powder and nanometer sol) added to ZnO varistor to stimulate grain growth and decrease E_(1 mA) was compared and analyzed. It is found that the effect of nanometer sol TiO_2 is better than that of the other two.
