The basis of technology proposed is use of a sol-gel method for preventing polycrystalline corundum fiber
from crystallization during heating to high temperature and for low-temperature synthesis of prescribed
phases in a corundum matrix with the aim of improving the operating properties of composite materials based
on corundum. As a result of firing a charge based on corundum powder modified with tetraethoxysilane and
polycrystalline corundum fiber modified with ethylsilicate-32 at 1360°C materials are created with very good
strength properties. The materials exhibit electrical insulation properties and are stable in ionized gas streams
at the level of known analogs as a result of creating self-reinforced mullite and β-SiC corundum matrix, reinforced with polycrystalline fiber and rapidly sintered due to presence of silicon oxynitride.
