ZrC Oxidization Mechanism In Air

摘要：

　　The ZrC oxidization mechanism in air was carefully investigated by the phase composition and grain morphology through DSC,X-ray diffraction and SEM respectively at different temperature.It was found that the oxidization of ZrC start at about 400 ℃ by oxygen atom entering the interstitial sites to substitute part of Carbon.Zr2O and ZrO2 can be formed at a temperature of about 600 ℃ and 1000 ℃ respectively.And ZrC will completely transfer to ZrO2 at 1000 ℃ for 5hrs.No obvious grain morphology change was found under 600 ℃.
