Abstract
Carbothermal reduction has been combined with nitriding of kaolin with various free SiO2 contents in the presence of additional silicon-bearing components under experimental industrial conditions to make β-sialons with Z = 0.73-3.78. It is possible to make a sialon with a given Z by means of additional silicon-bearing components, and also a sialon with Z = 2 directly from raw material kaolin. X-ray diffraction indicates that the composition inhomogeneity in the sialon is dependent on the content of free SiO2 in the mixture.
