Co3O4产品铜异物控制研究

Control Research on Copper Foreign Body in Cobalt Carbonate

采用硫酸钴及碳酸氢铵制备碳酸钴,再经过煅烧分解为Co3O4。研究了制备过程中铜的来源和控制方法,综合分析了控制Co3O4铜异物的方法,可对产品中铜异物的控制提供参考。

Cobalt carbonate was synthesized from cobalt sulfate and ammonium bicarbonate, and then decomposed into cobalt trioxide by calcination process. Through the study of copper source and control method in the process, the method of controlling cobalt tetroxide copper foreign body was comprehensively analyzed, and the reference was provided for the improvement of copper foreign body in the product.
