text: Starting from this finding, the invention provides a process for the manufacture of refractory magnesiachrome and chrome-magnesia products in which substances containing chromium oxide, especially chrome ore (chromite), have been mixed with magnesite, if desired sintered magnesite, and, advantageously after having shaped the mix, as in briquette form, it is sintered without fusion at a minimum temperature of 1700 C., preferably at least 1750 C., whereupon the sintered material is granulated and, if desired with the addition of sintered magnesia, used as refractory material in applications of the type referred to, this process being characterized by a combination of the following further features:
