Abstract

A chromite refractory material in which low melting point gangue has been converted into refractory material is prepared by intimately mixing chrome ore and dead burnt crystallized magnesium oxide, the magnesium oxide being greater than 12 1/2 per cent and preferably between 17 and 25 per cent of the mixture and sufficient or slightly more than sufficient to convert the gangue, grinding and tempering the mixture and shaping and turning the mass preferably at about 3000 DEG F. The chrome ore is heat treated at a temperature at least equal to that of the final burning together with all or part or without any of the magnesium oxide, the remainder being added prior to tempering. The low melting constituent of the chrome ore is by the treatment converted into the material known as forsherite. Specifications 219,423, [Class 22], 360,572, and 381,981 are referred to.
