Ceramic tiles made of grained technogenic crude

Sintering and properties of granular compositions with quartz-feldspar sand - waste from ore processing have been investigated. Low-melting binders have been developed that possess mineralogical compatibility to sand grains, reactive activity to their surface, favorable phase composition for sintering and ceramic properties. The effect of the composition, binder content, grain size composition of sand and firing temperature on the sintering of compositions for the manufacture of tiles for various purposes with imitation of the granular surface of natural stone (granite) and vitrified has been established.
