PREPARATION OF HIGH THERMAL EXPANSION COEFFICIENT PORCELAINS FUSED TO METALS J.P.Yang1,J.Q.Wu1 (1.Dept. of Inorganic Materials, South China University of Technology, Guangzhou 510640, China) Abstract:Usually the thermal expansion coefficients (TEC) of metals are higher than that of porcelains. In order to match the TECs in the case of coating porcelains on metals, high TEC porcelains......
