【Abstract】 The co sedimentation process for reuse of rejected ZnO varistors is presented. The selection of resolving acid, sedimental agent and pH value are discussed, meanwhile the effect of temperature on size of sedimented particles.The result shows that the particles obtained from co sedimentation process have better electrical performance than those obtained from ordinary process.更多还原
