摘要
Abstract
Large particles of aluminum-doped cobalt tetroxide were prepared by liquid phase precipitation-thermal decomposition.The effects of cobalt liquid flow,reaction temperature and reac-tion pH on impurity S content,solid density and supernatant Co content of large particles of aluminum-doped cobalt carbonate during liquid phase precipitation were investigated.At the same time,the influences of preheating temperature and feeding amount on the vibration density and cracking of large particles doped with aluminum cobalt tetroxide were investigated.The results show that the optimal conditions for precipitation of large particles of aluminum-doped cobalt carbonate are the feed flow of cobalt liquid 2.5 L/h,reaction temperature 45℃and pH 7.4.The optimal condi-tions for sintering are 30 m3/h and 15 kg/h cobalt carbonate feed rate.关键词
