Topaz-containing raw materials from the Kopna deposit are analyzed for chemical and mineral composition. Beneficiated rocks with different contents of topaz and topaz concentrates are classified as commercially promising for the manufacture of aluminosilicate refractories such as heat insulators and general-purpose products. The role of topaz in the quality improvement of clay-topaz compositions and processes of sintering and phase formation is discussed.
