FIELD: chemical technology.
SUBSTANCE: method for preparing β-sialone powder by carbothermal reduction of kaolin involves thermal treatment of charge in nitrogen atmosphere at 1710-1780°C for 5-25 min. Charge comprises a carbon component with particles size 20-500 nm. An average size of particles of prepared β-sialone powder can be regulated by using the disperse carbon component of charge with the required size of particles. Invention provides the development of rapid and simple in realization method for preparing β-sialone powder providing preparing β-sialone with the required size of particles.
EFFECT: improved preparing method.
