摘　　要：文章研究探讨了湿化学沉淀-高温煅烧、喷雾热解和直接热解三种规模化生产四氧化三钴工艺,在此基础上,从技术装备的成熟度、最终产品的物理化学指标以及对环境的影响等维度对比分析了上述工艺的优缺点。湿化学沉淀-高温煅烧工艺具有可精确调控产品微观形貌和粒度分布、容易实现原子级别均匀掺杂改性以及生产组织灵活等优点,在电池级四氧化三钴生产中一直占据主导地位。Three industrial production processes of tricobalt tetraoxide powder,namely wet chemical precipitation-high temperature calcination,spray pyrolysis and direct high temperature calcination have been studied.The advantages and disadvantages of the above processes were also discussed and compared from the dimensions of maturity of technical equipment,quality indexes of the final product and impact on the environment.The wet chemical precipitation-high temperature calcination process has the advantages of precise control of micro-morphology and particle size distribution of tricobalt tetraoxide powder,easy to achieve atomic level uniform doping modification and flexible production organization,and has always played a leading role in the production of battery grade cobalt tetraoxide.
