摘要

在国内外关于无机化合物热力学参数研究成果的基础上

采用近似方法得到硫铝酸钙热力学参数

其标准生成焓和标准自由能分别为8 300.8 kJ/mol和7 829.5 kJ/mol。根据分析计算

得到其在标准状况下的摩尔热容为514.3 kJ/(mol.K)。结合硫铝酸钙生成热力学分析了硫铝酸钙最佳生成途径

在1 350℃其生成达到极大值

转化率达到66.66%。

Abstract

On the basis of study results concerning thermodynamic parameters of inorganic compounds at home and abroad

the thermodynamic parameters of calcuim sulfoaluminate have been obtained by using the approximate method

the standard formation enthalpy and the standard free energy to be 8300.8 kJ/mol and 7829.5 kJ/mol respectively

and based on analysis and calculation

the mol thermal capacity under standard condition has been obtained.Combining with thermodynamics concerning formation of calcium sulfoaluminate

the optimal formation way of said substance has been analysed

its formation reaches max.value at 1350 ℃

conversion rate reaching 66.66%.
