INFLUENCE OF FELDSPAR CONCENTRATE ON PHASE COMPOSITION OF FLOOR TILES BASED ON NON-FERROUS METALLURGY WASTES
Tiles for floors on the basis of waste of nonferrous metallurgy of clay part of «tails» of gravity of zircon-ilmenite ores (GCI) as a clay component, and a by-product of production of rare earth metals (PSHK) as a melt, for decrease in temperature of firing are received. The introduction of PSHK (feldspar concentrate) into the compositions of ceramic masses at a firing temperature of 1100 °C eliminates the formation of cristobalite, as it transfers quartz into the melt. PSHK contributes to the production of floor tiles with high physical and mechanical properties at a firing temperature of 1100 °C.
Keywords: feldspar concentrate, clay part of gravity «tails», floor tiles, phase composition, mullite, quartz, glass phase.
