Abstract:
Al 4 SiC 4 – Al – Si composites were synthesized using a mixture of calcined bauxite, silicon carbide and carbon black as the starting materials. Al 4 SiC 4 began to form at 〉 1 600 °C and Al and Si were identified at 1 800 °C. Al and Si formed only when silicon carbide was in excess of the amount of SiC necessary to form Al 4 SiC 4 . The synthesized powders consisted of irregular plate-like crystals and the surfaces were molten-like. The oxidation characteristics of Al 4 SiC 4 – Al – Si composites as antioxidants were better than the oxidation characteristics of pure Al 4 SiC 4 , since their action took place mainly at 400 – 700 °C (Al – Si) and above 850 °C (Al 4 SiC 4 ).
