N2 - An inclusion compound between zeolite and polyacrylonitrile has been applied as a precursor for the carbothermal reduction process. By heat treatment at 1400 to 1600° C in N2, β-sialon was mainly obtained. The X phase, α-Si3N4, the 15R-AlN phase, AIN, and mullite also formed under certain firing conditions. On the other hand, α-Si2N4 was detected as the principal crystalline phases as well as β-sialon in the products from zeolite-carbon mixtures. Hence, the use of the inclusion compound was advantageous for β-sialon production in the conversion of zeolite to nitrides.
