FEEDSTOCK COMPOSITION FOR PRODUCING POROUS PERMEABLE CERAMIC MATERIAL FEATURING HIGH HEAT RESISTANCE

摘要

FIELD: ceramic products for use in manufacture of filters and catalyst carriers for metallurgy, chemical industry and mechanical engineering. SUBSTANCE: proposed feedstock composition comprises following components, wt.%: roasted talcum 16-20, alumina 9-12, clayey component (i.e. clay + kaolin) 34-38, quartz sand 17-19, feldspar 11-13, porcelain scrap 4-5. EFFECT: products made of proposed composition have good operational properties due to higher heat and corrosion resistance. 1 dwg , 3 tbl
