Carbon-ceramic composite materials with protective erosion-resistant coatings

Results are presented for the development of production examples of creating refractory materials and structures made from them for the metallurgical industry from carbon and ceramic carbide-forming substances. Practical recommendations are proposed for creating integral structures of new refractory materials for high-temperature processes with a limiting operating temperature of the corresponding carbide protective coatings that exceeds the operating temperatures in air for graphite structural materials. by more than 1000°C. Experimental studies are performed on 16 prepared reactor units for high-temperature chemical processes with an absolute pressure within a reactor of 0.3 MPa and an operating temperature of 900°C. All of the technical specifications for a chemical reactor for air tightness are fulfilled with a reserve of operating capacity. __________ Translated from Novye Ogneupory, No. 2, pp. 47–53, February, 2007.
