FIELD: building industry and materials. ^ SUBSTANCE: invention relates to manufacturing building ceramics and can be used in making facing tiles. The raw mixture for making facing ceramic tile comprises carbon enrichment rock treated at 570-600°C, clay and slurry fraction in enrichment waste of iron ores as a fusing agent that comprises the following components, wt.-%: SiO2, 42.45; Al2O3, 14.54; CaO, 14.88; MgO, 4.52; FeO, 8.06; Fe2O3, 9.46; SO3, 0.98; R2O, 3.25; MnO, 0.49; TiO2, 0.73, and P2O5, 0,64 in the following ratio of components, wt.-%: carbon enrichment rock treated at 570-600°C, 70-90; clay, 5-20, and slurry fraction in iron ores enrichment, 5-10. Invention provides reducing shrinkage deformations, water absorption of tile and energy consumption in its manufacturing. ^ EFFECT: valuable technical properties of raw mixture. ^ 2 tbl |
