The diagram showing true relationships be-tween chemical potential of oxygen and compositions for the non-stoichiometricMo and MoO_2 equilibrium at 750, 850 and 950℃ is given. And the correction val-ues for the standard free energy of formation of MoO_2 are calculated by Smiltens'integration. In order to overcome the difficulty of the integration used for puremetal side, the Sieverts' law constant is introduced. It is shown that the correctionvalues effect little change in the standard free energy of formation of MoO_2. Key words： non-stoichiometric MoO_2    oxygen potential line    free enthalpy    Sieverts' law constant    Smiltens' integration 收稿日期: 1988-01-18      基金资助:中国科学院科学基金 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 方正 陈新民 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1988/V24/I1/111 1 方正,陈新民.中南矿冶学院学报,1982:(4) :1 2 Srivastava S C,Seigle L L.Metall Trans,1974;5: 49 3 方正,陈新民.(待发表) 4 Kleykamp H, Supawan A.
