Conclusions
The new technology for corundum-graphite refractories with a pitch-ethyl silicate bond means we can exclude the harmful action of the volatile components of the pitch, A rise in firing temperature contributes to a greater yield of silicon carbide, and consequently to the production of a material with a greater strength and resistance to oxidation. The synthesis of silicon-carbide bond in the newly developed refractories greatly improves the properties of the refractory compared with the clay bond. Study of the corundum-graphite refractory materials shows that they are sufficiently deformative, and have a relatively high breakdown strength.
