Phase Phase Composition and Melting Features of Mineral Raw Material from Ukrainian Deposits used for LAS-Ceramics Production

This paper describes how Li-glass is obtained and studied. Using this glass, Li2O-Al2O3-SiO2 – based glass-ceramics materials are produced. They play an important role in industry as materials with specific properties. Glass-ceramics materials feature high strength, low coefficient of thermal expansion, chemical and thermal stability, refractoriness etc. To obtain LAS-сeramics, we obtain separate fraction petalite, study their chemical composition, select and calculate the composition of the Li-glass charge. In addition, the heat treatment of the obtained received samples is carried out.
