Ceramic Tiles Made Of Granular Technologenic Raw Materials

Sintering and properties of granular compositions containing quartz-feldspar sand (ore processing waste) are studied. Low-melting binders having mineralogical compatibility with the sand grains, reaction activity toward their surface, and a favourable phase composition (regarding sintering and ceramic properties) are developed. The effect of the mixture composition, binder content, grain composition of the sand, and firing temperatures on the sintering of mixtures intended for production of tiles for various purposes is established. The tiles thus obtained successfully imitate the surface of granite-like natural stones.
