Thermochemical Synthesis of Sialon Using Low-Temperature Plasma Radiation and a Bright Pulsed Beam of a Powder Mixture of AlN and Si3N4

A study was made of the effect of low-temperature plasma and pulsed electron beam irradiation on a mixture of silicon and aluminum nitride powders. It was found that as a result of irradiation with high-enthalpy plasma flux on the studied sample a thermochemical reaction occurred with the formation of a multiphase mixture in which the main product is β-SiAlON. Irradiation with a pulsed electron-pulse beam led to the formation of compounds based on β-SiAlON with different chemical compositions. The morphology of particles on the surface of irradiated samples was determined. The parameters of the crystal structure of compounds based on SiAlON is calculated.
