摘要
采用Ｘ射线衍射分析、差热分析，对硝酸铜、硝酸锌混合溶液与碳酸钠溶液共沉淀过程的机理进行了研究。试验结果表明，Ｃｕ（ＮＯ３）２、Ｚｎ（ＮＯ３）２与Ｎａ２ＣＯ３共沉淀的反应机理是初始生成的Ｃｕ２（ＯＨ）３ＮＯ３与Ｎａ２Ｚｎ３（ＣＯ３）４进一步反应生成（Ｃｕ，Ｚｎ）５（ＣＯ３）２（ＯＨ）６。
n this paper,the coprecipitation mechanism of a mixed solution of copper and zinc nitrates with a solution of Na2CO3 has been studied by means of XRD、DSC and TGThe results show the coprecipitation mechanism is the formation of (Cu,Zn)5(CO3)2(OH)6 from further reaction between the initially formed Cu2(OH)3NO3 and Na2Zn3(CO3)4
