摘要
根据基础热力学数据,对C,SiC,Mn,Si,Al,Fe等还原剂还原氧化钼和钼酸钙进行了热力学分析,通过热重实验研究了还原剂（C或SiC）、抑制剂（CaO）对MoO3挥发的抑制效果.结果表明,1300℃下纯MoO3挥发率达85.68%,添加CaO或还原剂后挥发率约为20%,同时添加还原剂和CaO时挥发率约为10%.
Based on the basic thermodynamic data, the thermodynamic analysis of the reducing molybdenum oxide and calcium molybdate by reducing agents such as C, SiC, Al, Mn, Si and Fe. The thermogravimetric experiments was conducted to study the effect of additives including reducing agent of C or SiC and inhibitor of CaO on volatilization of molybdenum oxide. The results showed that the volatilization rate of pure molybdenum trioxide was 85.68% at 1300 ℃, and the addition of CaO or reductant （C or SIC）, the volatilization rate was about 20%, while with the addition of reducing agent and CaO, molybdenum oxide volatilization rate was only about 10%.
