Thermodynamic analysis of slag system with a particular emphasis on hydration with water vapor was conducted for the systems CaO+P2O5+FeO and binary alkaline sulphates. Kinetic studies were also made for the reaction CaO+H2O+=Ca(OH)2 at steam pressure of 0.1 to 0.3 atm and temperatures between 100 and 400 degree centi-grade. Kinetic analysis revealed that the rate controlling step for this reaction would be chemical reaction between solid lime and water vapor.

对CaO+P2O5+FeO和二元碱性硫酸盐体系的渣系进行了热力学分析，重点分析了渣系与水蒸气的水化作用。本文还对CaO+H2O+=Ca(OH)2反应在蒸汽压力为0.1 ~ 0.3 atm，温度为100 ~ 400℃的条件下进行了动力学研究。动力学分析表明，该反应的速率控制步骤是固体石灰与水蒸气的化学反应。
