摘　　要：以硝酸钴为钴源,碳酸铵为沉淀剂,采用沉淀法制备四氧化三钴粉体。采用TG、XRD、IR、激光粒度分析仪等对前驱体碱式碳酸钴和产物四氧化三钴进行了表征及分析。研究了焙烧温度、反应物浓度和反应时间等因素对产物的影响。The cobaltosic oxide powder was prepared by precipitation method with cobalt nitrate as the cobalt origin and ammonium carbonate as the precipitator.The precursor basic cobaltous carbonate and cobaltosic oxide product were characterized and analyzed by TG,XRD,IR and laser particles analysis.The effects of the calcination temperature,concentration of reactant and reaction time on product were studied.
