用ＤＴＡ和ＸＲＤ方法研究了高纯ＷＳ２在空气中的氧化机理，并用Ｄｏｙｌｅ－Ｏｚａｗａ法和Ｋｉｓｓｉｎｇｅｒ法测定了氧化反应的活化能为１００．１ｋＪ／ｍｏｌ，反应级数为０．８０．ＷＳ_２分子氧化主要以ＷＳ_２→Ｗ_３Ｏ→ＷＯ_２→Ｗ_（１８）Ｏ_（４９）→ＷＯ_（２．９）→ＷＯ_３步骤连续进行。氧化反应的最终产物为ＷＯ_３。
The oxidation mechanism of high purity WS2 in air was studied by DTA and XRD. The activation energy of oxidation reaction was 100.1kJ / mol and the order of reaction was 0.80 by Doyle-Ozawa method and Kissinger method. WS 2 molecular oxidation mainly WS_2 → W_3O → WO_2 → W_ (18) O_ (49) → WO_ (2.9) → WO_3 step continuously. The final product of the oxidation reaction is WO_3.
