| Abstract: | With the mechanisms of CAD(Chemical Vapour Deposition) used to prepare superfine, the experiment research on preparation of superfine ZnO powder from the low grade of zinc oxide ore by pyrometallurgical method, have been carried out; Particle size, X ray diffraction and distribution of ZnO powder have been measured; The effect of cooling strength and collector on particle size and distribution of ZnO powder have investigated; The reasons of reuniting appearance have discussed, and trial condition control size of ZnO powder. |
