  SiAlONs are solid metal oxide solutions in nitrides.Area of their presence is considered in fourcomponent system-Si3N4-AlN-Al2O3-SiO2.In the present paper SiAlON-containing nano-composite was obtained through alum-thermal process on the base of kaolin and aluminum nano-powder in the nitrogen medium,by the reactive baking method.The advantage of this method is that compounds,which are newly formed thanks to interaction going on at thermal treatment: Si3N4,Si,AlN are active,which contributes to SiAlON formation at relatively low temperature,at 1250-1300℃.
