Semchenko [et al.] // Refractories and Industrial Ceramics. – 2015. – Vol. 56, iss. 2. – P. 180-183.https://repository.kpi.kharkov.ua/handle/KhPI-Press/46662The 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.enmullitemodified fibertetraethoxysilanesilicon oxynitrideArticledoi.org/10.1007/s11148-015-9808-2
