Elementoxanealumoxanes – modifiers of silicon carbide ceramic composites components

Abstract

Pre-ceramic organoelementoxanealumoxane oligomers whose pyrolysis results in oxide ceramics of multicomponent composition: aluminum yttrium (xY2O3·yAl2O3), yttrium aluminum silicate (xY2O3·yAl2O3·zSiO2), yttrium aluminum magnesium (xY2O3·yAl2O3·zMgO) ones, are modifiers of silicon carbide based composite materials that increase their resistance to high temperature oxidation.
