摘要
用恒温热重法研究了CaCO_3在CaCO_3-CuO和CaCO_3-Bi_2O_3体系中的分解动力学,求出CaCO_3的分解方程式。实验结果表明:在上述两体系中,CaCO_3的表观分解活化能均为120 kJ·mol^(-I),并初步分析了CaCO_3的分解机理。
The kinetics of decomposition process of CaCO3 in CaCO3-CuO and CaCO3-Bi2O3 systems was studied thermogravimetrically at constant temperature so as to find out the differential equation of CaCO3 decomposition. Experimental results showed that the apparent activation energy in both systems is 120 kJ·mol-1.
