摘    要:由Ni(OH)2在升温过程中的TGA和DSC曲线,研究其热分解反应的动力学,实验结果表明,Ni(OH)2粉体从489K时开始分解,626K时分解完毕,反应的活化能为125.25kJ/mol。化学反应是分解过程的控制环节。

关 键 词:热分解动力学  非等温技术  氢氧化镍  氧化镍粉

Abstract:The kinetics of thermal decomposition of Ni(OH)2 powders is investigated by TGA and DSC techniques.The experimental results show that the Ni(OH)2 powders decompose considerably at 489 K and thedecomposition is finished at 626 K. The product, being verified by XRD,is NiO. The reaction activation en-ergy is 125.25 kJ/mol. And the controlling step of the reaction is chemical reaction.
Keywords:Ni(OH)_2  thermal  decomposition  kinetics
