Abstract

The effect of refractory additives (alumina, alumosilicate mortar, and zircon concentrate) on the properties of SHS refractories based on silicon carbide is studied. It is shown that introduction of the additives favors enhancement of the compressive strength of the material. The enhancement is especially efficient in the case of an admixture of zircon concentrate. The resistance of the silicon carbide material to corrosion in slags of titanium production and iron foundry production is improved when the content of the additives is increased from 5 to 30%. The addition of zircon concentrate allows the slag-resistance of the silicon carbide material to be increased by a factor of 6, while the effect of alumina and alumosilicate mortar is less pronounced.
