RAW MIXTURE FOR MAKING CERAMIC WALL ARTICLES

摘要

FIELD: chemistry. ^ SUBSTANCE: raw mixture relates to compositions for making ceramic wall articles. The raw mixture (in terms of dry substance) contains the following components in wt %: Microsilica from production of crystalline silicon 84.2-84.8, spillage from broken spent carbon lining of electrolysis cells 14.8-15.0, tall saponified fatty acids (TSFA) 0.2-1.0. The raw mixture is moistened to moulding-moisture content of 23-23.8% with an aqueous solution of TSFA. The moulded and dried articles are roasted at 850-950C. ^ EFFECT: increased strength and strength-weight ratio of articles. ^ 1 ex, 2 tbl
