Physicochemical Study of Alumochromium-Containing Refractories Developed by Self-Propagating High-Temperature Synthesis

Abstract

Results are given for a study of the main physicochemical properties of a new alumochromium-containing refractory composition developed by self-propagating high-temperature synthesis. The basis of the chemically stable refractory materials obtained is production waste, i.e., ferrochrome slag, and chromite concentrate. The good chemical stability, refractoriness, mechanical strength, hardness, and wear resistance govern the possibility of use in preparing corrosion-resistant, refractory objects, plasters, and concretes.
