Abstract
A process for the manufacture of bonded silicon carbide refractories comprises forming a mixture of silicon carbide and a bond which is non - reactive with silicon carbide at temperatures up to the fusing point of the bond and which has a fusing point between 1800 and 2100 DEG C., and heating the mixture at least to the temperature of incipient fusion of the bond, in an atmosphere which is inert with respect to both the carbide and the bond. Examples of suitable bonds are alumina, magnesian spinel, mullite and compounds of alumina, magnesia and silica, alumina lime and silica or alumina, magnesia and lime. A carbon monoxide atmosphere is satisfactory for use with a bond of alumina, or mixtures of alumina, magnesia and lime, but where silica is a principal constituent of the bond, a more inert atmosphere such as nitrogen or helium is preferable.
