About author:Dr. Valeriy Martynenko is a director of the Ukrainian Research Institute of Refractories, named after a very famous scientist in the refractory field, academician A.S. Berezhnoy. He has worked in the institute for more than 45 years, carrying out research in the field of silica, alumina, zirconia, and chromia refractories, and their industrial applications. He has published over 400 scientific works and 80 patents. He is a member of the American Ceramic Society, as well as a member of the editorial board of the magazines Refractories Worldforum (Germany) and China's Refractories (China). He is also the editor-in-chief of the collection Scientific Research on Refractories and Technical Ceramics, Collection of Scientific Papers, published by the institute.

Abstract

Abstract: The microstructure and phase composition of high-alumina, chromic oxide, and AZS/Cr refractories containing 30% and 60% (by mass) Cr₂O₃ after exposure to aluminaboronsilicate glasses and basalt melts depending on the type of melts and temperature have been studied. The mechanisms of refractory corrosion by the used melts and the factors contributing to the inhibition of corrosion development have been investigated by the method of petrographic analysis. On the basis of obtained results, the use of high-alumina, chromic oxide, and AZS/Cr refractories in the sections of glass furnace linings, experiencing the intensive impact of aluminaboronsilicate glasses and basalt melts, has been confirmed and scientifically substantiated.

Key words: high-alumina refractories, chromic oxide refractories, AZS/Cr refractories, microstructure, phase composition, aluminaboronsilicate glasses melts, basalt melt
