AbstractThe thermal oxidation process of stoichiometric MoS2 and nonstoichiometric “Mo2S3”, together with the kinetics of oxidation of MoS2, were studied by using TG and DTA techniques in the Po2 range 1-0.0890 atm. MoS2 was oxidized completely to MoO3 in one step: $$MoS_2 + 7/2O_2 \to MoO_3 + 2SO_2 $$ Irrespective of Po2 and the heating rate, “Mo2S3” was oxidized finally to MoO3, via the following four steps: $$\begin{gathered} ''Mo_2 S_3 ''\xrightarrow{I}\gamma - Mo_4 O_{11(sur)} + ''Mo_2… Expand
