摘要
本文从热力学方面讨论金属Al还原Cr2O3反应,认为其是自蔓燃反应,在特定条件下该反应生成金属陶瓷而不生成CrO。采用DTA确定反应发生温度,并从DTA曲线近似计算该反应的活化能E=1093.822kJ/mol。
In this article, the reduction reaction of chromium oxide by metal A1 is discussed from thermodynamic factor, and then confirm its being a self-propagating high-temperature synthesis. The production is ceramet other than CrO at special condition. And then the reaction temperature is confirmed by DTA technical, further more the activation enthalpy is calculated approximately by DTA curve.
