Preparation of Coarse Cobalt Powder from CoC_2O_4·2H_2O by Circulatory Oxidization-Reduction AITranslate
Abstract AITranslate
CoO was prepared by the thermal decomposition of CoC2O4 · 2 H2O in the air, and then reduced in the hydrogen gas with a 99. 999% purity and --40℃ dew point to obtain cobalt powder. The cobalt powder was oxidized in the air to obtain CoO again. The above processes of oxidation and reduction were circularly carried out. The product was characterized by scanning electron microscopy and laser particle size analyzer. The results show that coarse cobalt powder is obtained through three cycles of oxidation and reduction,of which the particles of 12-26 μm size distribution accounts for 93.53%.
