The reason for the strong nature of silicon carbide-reinforced alumina than pure alumina has to be determined. Concept introduction: Ceramics are non-metallic, inorganic, non-molecular solids. It comprises both crystalline materials (quartz) and amorphous materials (glass). Pottery and porcelain are made up of silicate ceramics by applying high temperature to aluminosilicate clays. The properties which differentiate ceramics from metals are high melting point, hardness, stiffness, less dense, resistant to wear and resistant to corrosion. Ceramics such as silicon carbide and silicon nitride are stable upto 1400- 1500 0 C and does not oxidize in air because they are completely oxidized.
