Abstract

In the course of the work with purpose of the obtaining by sol-gel method protective high-temperature coatings of Y2O3–Al2O3–SiO2 system technique of the preparation film-formation solution was perfected, influence of the components ratio in initial solution on physic-chemical characteristics of solutions, gels and sintered materials was studied, phase formations were studied. Application capability of this coatings to protective SiC materials at high temperature was investigated.
