    Abstract

    Both silicon carbide and aluminum silicon carbide have simultaneously been obtained directly from naturally occurring aluminosilicate by carbothermal reduction for the first time. A precursor of a montmorillonite-polyacrylonitrile (PAN) intercalation compound was heated at 1700 degree C in Ar. For comparison, montmorillonite-carbon mixtures were similarly heated. alpha -SiC, beta -SiC, and Al//4Si//2C//5 formed from the montmorillonite-PAN intercalation compound. Mainly alpha -Al//4SiC//4 was obtained with ternary carbides from the montmorillonite-carbon mixtures in addition to a large amount of beta -SiC. Hence, aluminum silicon carbide formation was affected by the mixing condition of the starting materials.
