中文摘要：

通过CaCl2添加剂对KAlSi3O8-CaSO4-CaCO3体系研究反应温度和反应时间的影响研究，结果表明：随着CaCl2加入量的增多，体系的反应温度下降，反应时间缩短，当CaCl2的加入量为10％时，反应温度可降至1000℃，反应时间降至25min，此时KAlSi308的转化率仍可高达83．24％。研究CaCl2的加入对KAlSi3O8-CaSO4-CaCO3反应体系动力学过程的影响，得出反应体系符合金斯特林格动力学方程：Fx（G）=1—2／3G-（1-G）2／3=KKt，反应受扩散过程控制，计算出当CaCl2的加入量为10％时，体系的表现活化能可从原来的128．921kJ／mol下降至58．320kJ／mol。

英文摘要：

Influence of CaCl2 agent addition on the KAlSi3O8-CaSO4-CaCO3 system was determined by relationship between percent conversion of K-feldspar and calcination temperature or calcination time. It was showed that calcination temperature or calcination time reduced with gradual addition of CaCl2 agent. When the concentration of CaCl2 agent in the reaction system enhanced 10%,the calcination temperature was reduced to 1 000 ℃ ,and the calcination time was shorten to 25 minutes. Then the percent conversion of K-feldspar still reached up to 83.24%. Accordingly,the dynamical process about KAlSi3O8-CaSO4-CaCO3 system with addition of CaCl2 agent was researched. This reaction was in accordance with the Ginstling dynamical equation 1-- 1/3G--（1--G） 2/3= KK t, which was controlled by solid phase diffusion process. The apparent activation energy Ea in the original system was decreased from 128. 921 0 kJ/mol to 58. 320 kJ/mol when 10% CaCl2 agent was added into this system.
