Titanium-Alumina Slag – Semifunctional Technogenic Resource of High-Alumina Composition. Part 2. Use of Ferrotitanium Slag for Producing Refractories in Metallurgy and Other Branches of Industry1

Abstract

Scientific research work performed using titanium-alumina slag starting from the 1940s is reviewed. It is shown that use of titanium-alumina slag as a sintering additive makes it possible to improve the functional properties of various refractories, magnesite (periclase) powder, and some forms of refractory concrete. The slag serves as a secondary raw material or for TiO₂ preparation, and is also used successfully in manufacturing acid-resistant materials.
