Dolomite Refractories, and Their Potential as Substitutes for Imported Chromite.
MISSING :18 pages
To help reduce the nation's dependence on imported chromite, the Bureau of Mines is conducting research on the use of dolomites as an alternate material. Dolomite is a plentiful domestic resource and offers certain advantages as a refractory raw material. A review of the literature has indicated that there are many sources of high- purity dolomite in this country and that European nations use a greater proportion of dolomite refractoreis, primarily in steelmaking than the United States. The Bureau of Mines characterized 14 domestic dolomites as to chemistry, density, mineralogy, microstructure, and thermal behavior, to develop baseline data on their suitability as refractory raw materials.
