摘　　要：Magnesiu-Calcia materials containing 22 -53 wt% CaO hare been investigated Jot refinery slag corrosion and penetration resistance by Scanning Electron Microscopy （ SEM） .nd XRD. The corrosion and penetration resistance of MgO-CaO materials is enhanced with the increase of CaO content in specimens. It can be explained that, with increase of CaO content, the specimens reacted will＋ slag form higher melting point minerals of C3S ant C2S, creating a dense surface layer, which stopped others from penetrating further. Thus , the corrosion and penetration resistame was improved. No matter what kinds of slag were chosen, the depth of penetration decreased will＋ increase of CaO con,tent.Magnesiu-Calcia materials containing 22 -53 wt% CaO hare been investigated Jot refinery slag corrosion and penetration resistance by Scanning Electron Microscopy （ SEM） .nd XRD.
