FIELD: chemistry.
SUBSTANCE: invention relates to obtaining protective high-temperature antioxidation coatings based on ceramic suspensions or organoyttrium oxane alumoxane siloxanes for producing a composition of Y2O3-Al2O3-SiO2 on ceramic-matrix composites of the type C/C and C/SiC to obtain composite materials that are high temperature-resistant in an oxidative atmosphere. The disclosed suspension for obtaining protective high-temperature antioxidation coatings contains binder - toluene solution of organoyttrium oxane alumoxane siloxane and filler - mixture of fine refractory powders of Al2O3, Y2O3, SiO2, with the following ratio of components, wt %: binder (toluene solution of organoyttrium oxane alumoxane siloxane) 30-50, Al2O3 14-20, Y2O3 23-33, SiO2 - the balance up to 100.
EFFECT: high heat-resistance of coated composite materials in an oxidative atmosphere.
