Chemical composition, physicomechanical properties, mineral composition, and crystallographic properties are specified for high-alumina bauxites (predominantly Chinese) applied to refractory manufacture, prepared by HCBS-technology. Technology is developed for HCBS preparation of composite composition (bauxite + very fine quartz glass, i.e., HCBS) and refractories based on them with improved thermomechanical properties. © 2015 Springer Science+Business Media New York

Results are provided for a comprehensive study of the thermal stability, composition, and properties of sin-gle-fraction fuzed material produced by OAO Dinur and supporting suppliers before and after heat treatment at 1400 C. A favorable effect of firing on reducing macro-and microstructural defects of fuzed grains and a significant increase in thermal stability is established for materials (apart from silica glass). © 2012 Springer Science+Business Media New York.
