Abstract

Refractory substances are made by mixing chromium ore with a magnesium compound, e.g. magnesite, which has been melted or sintered at a temperature of about 1500 DEG C. or more, and firing the mixture. The chromium ore employed preferably contains more than 30 per cent of chromium oxide and the finished product between 10 and 80 per cent. Organic binders and other ingredients may be added.
