采用TG、DTA、DTG等热分析手段研究了碱式碳酸锌热分解过程，热分析研究结果显示, Zn₅(CO₃)₂·(OH)₆为一步分解而得到纳米氧化锌，研究得到的机理模型证明其热分解过程符合随机核化机理。利用XRD，TEM等测试手段对纳米氧化锌的结构和形貌进行了表征，结果表明，通过Zn₅(CO₃)₂·(OH)₆热分解方法可以获得结晶性及分散性良好、粒径分布窄、粒度约为10nm左右的纳米氧化锌。

The thermal decomposition process of zinc hydroxide carbonate was studied by thermal gravimetric analysis (TG), differential thermal analysis (DTA) and derivative differential thermal analysis (DTG). It was shown that water and carbon dioxide were formed at the same time and zinc hydroxide carbonate decomposed into zinc oxide. The mechanism model was deduced and was inferred as random nucleation mechanism (Aurami equation II ). The structure and morphology of nanometer-sized zinc oxide by using thermal decomposition method were investigated by means of XRD and TEM. The study indicated that the well-crystallized and dispersed, narrow-sized, nanometer-sized zinc oxide of about 8-10nm was available by using this method.
