| Abstract: | In the paper,the principle and method that ZnO varistor composite additives are prepared by means of chemical coprecipitation are expounded.It is discussd that the engineering feasibility of eight reagents are used as precipitants.It is shown as experiment results that suitable composite precipitants and precipitation conditions is important to improve the surge current absorption capability,decrease the voltage ratio,sinter temperature and production cost.The prepared method is worth using in more region of various ceramic materials. |
