摘要
本文采用TG、DTG方法研究了Ni(OH)2 在H2 中还原制备超细镍粉过程的反应机理。并用Doyle -Ozawa法和Kissinger法测定了还原反应的动力学参数 ,反应的活化能为1 0 0 . 2 5kJ/mol,反应级数为 1 . 0 8。还原反应为一步完成的。
The TG and DTG techniques were used to research the reduction process of Ni(OH)_2 in H_2 to prepare ultrafine nickel powders.The activation energy and the orders of reduction reaction has been obtained according to Doyle-Ozawa and Kissinger methods.The reduction reaction occurs in one step.
