摘要 In order to restrain the carbon pollution, the feasibility of CaZrO3 coating was studied. The precursor powder was synthesized via solid-state reaction using metal calcium as a raw material. The protective coating on graphite was prepared by impregnation sintering method, and the effects of slurry viscosity, graphite density and coating thickness for coating were compared. The phase composition and microstructure of coatings were characterized, and the thermodynamic process was analyzed when the coating composition changed from CaZrO3 to ZrC. The results show that vacuum sintering can result in the decomposition of CaZrO3 and an intact ZrC coating with beautiful porous structure can be obtained.
