本文报道MoO_2部分非化学计量区域研究结果,并综合Mo-MoO_2平衡及氧在金属Mo中溶解度数据,绘制750,850及950℃下非化学计量Mo与MoO_2平衡真实氧位线;同时对MoO_2生成自由焓进行非化学计量的Smiltens修正.为解决Smiltens修正积分应用于纯金属边时的困难,积分中引入了Sieverts常数.计算表明,Smiltens修正量对MoO_2生成自由焓值无明显影响.

The interaction coefficients of Ca.Ti and Mg in the dilute Sn-based solution have been de- termined at 1500℃.Experimental measurements were taken by equilibrating the slag-alloy systems with metallic Sn as flux and graphite as reducing agent under Ar atmosphere mixed with different portion of CO.It was found that a considerable error may produce if the coefficients of ε_(Ca)~(Ca),ε_(Mg)~(Mg)and ε_(Ti)~(Ti)in the molten Sn were neglected when the activities of the components CaO,MgO and TiO_2 in the slags were estimated by this method.
