| Abstract: | Improvement of ZnO powders for electronic materials with wet chemicalmethod NH_3 technique is studied in this paper. The main technical data such asroasting temperature and milling time are determined by X-ray Diffraction analysis andSEM analysis. The existing states of ZnO powders before and after being processed arestudied with SEM analysis, BET analysis ,as well as Particle Size and Particle Size Dis-tribution analysis. The test results of manufacturing ZnO varistors demonstrate thatZnO varistors with excellent pre-breakdown characteristics can be obtained from ZnOpowders processed with NH_3 technique. |
