SiC material is a kind of material with excellent properties, in order to inhibit it's oxidation behaviour and prolong the service life of the material during the process of using, the oxidation behaviour of three kinds of SiC materials containing different amounts of Cp in the three temperature ranges from 400oC to 1100oC is studied in this paper. It emphatically analyzes the relations among Cp/SiC's quality change fraction in air and oxidation temperature, oxidation time, Cp/SiC's apparent porosity and oxidation temperature, Cp/SiC's bending strength and oxidation temperature, oxidation time. It is concluded that the Cp content of SiC is the key factor to influence the strength and oxidation behaviour of composite materials and the kind of SiC composite ceramics which add Cp can improve oxidation resistance of the materials.
