TG和DTA研究KClO_4—CuO混合物热分解

TG and DTA Study on the Thermal Decomposition of KClO_4—CuO Mixtures

本文采用TG和DTA方法研究了CuO对KClO_4热分解的催化作用,TG和DTA曲线证明了CuO的加入导致了KClO_4固态热分解的加速及分解温度的显著降低。CuO的这些作用随其在KClO_4中的混合比(Wt％)增加而增大。KClO_4经CuO催化热解后的固体产物由x衍射确定为KCl,热解过程的有关动力学参数也求算出。

The catalytic effect of CuO on the decomposition of KClO_4 was studied by TG and DTA. DTA and TG curves show that the addition of CuO leads to an acceleration effect on the solid-state decomposition of KClO_4 and a decreasing in its decomposition temperature with an increasing in the mixing ratio of CuO. XRD of the samples obtained after DTA experiments show that thermal decomposition of KClO_4 mixing CuO leads to the formation of KCl as final solid-state product.
