摘要
研究了合成Co3O4前驱体的几个影响因素。实验选用氯化钴作为原料，碳酸钠作沉淀剂，Co离子浓度为60～70g／L，氯化钴／碳酸钠（摩尔比）比值在0．60-0．70之间，加液方式选择将沉淀剂加入氯化钴液中，沉淀时pH值控制在9．0～9．6。实验表明，在上述条件下，可以获得较好的Co3O4前驱体。
Some factors which affected the synthesis of Co304 precursor were studied. Cobalt chloride was selected as raw material, sodium carbonate as precipitant, the concentration of cobalt ion was 60 -70 g/L, the ratio（ mol ratio） of cobalt chloride and sodium carbonate was among 0.60 - 0.70, precipitant was added into cobalt chloride solution and pH value was controled among 9.0 - 9.6 during precipitation, better Co3O4 precursor can be obtained.
