Title
Thermodynamic Study of Oxidation of Molybdenum Sulfides
김준수Jun Soo Kim, 오재현Jae Hyun Oh
Abstract
Oxidation reaction of molybdenum sulfides has been studied by thermodynamic analysis of the diagrams of Molybdenum-Sulfur-Oxygen System. The results obtained in this investigation are as follows; 1) Partial pressure diagrams of Mo-S-O system were represented by thermodynamic calculations between 673˚K and 923˚K. 2) The followings are feasible reactions among the oxidation reactions of molybdenite. MoS₂＋3O₂= MoO₂＋2SO₂ MoO₂＋0.5O₂= MoO₃ MoS₂＋6boO₃= 7MoO₂＋2SO₂ 3) During the roasting of molybdenite in air, the oxidation reaction occurs through the following steps. MoS₂→MoO₂→MoO₃
