Refractory Dolomite Raw Materials.
Proc Raw Materials for Refractories Conf Univ of Alabama 2/8- 9/82 1(1):220-253
As one of its goals to reduce the nation's dependence on imported strategic and critical materials, the U.S. Bureau of Mines is conducting research to encourage the use of plentiful domestic dolomitic resources. Greater use of our dolomite materials in a variety of refractory processes could reduce our dependence on imported chromite and more expensive seawater periclase. A review of the literature on dolomite refractories has indicated that the United States has traditionally used less dolomite refractories than European countries. Characterization studies of 14 domestic dolomite ores, which included chemical and mineralogical analyses, density and hydration determinations, and microstructure and thermal decomposition evaluations, have shown that there were noticeable differences in the hydration, microstructure, and thermal behavior of the various ores.
