FIELD: chemistry.
SUBSTANCE: crude mixture for making ceramic wall articles contains carbonised loam and an aqueous suspension which contains hydrated lime, gas-cleaning dust from production of ferrous alloys, saponified tall oil fatty acids and brine, with the following ratio of components, wt %: carbonised loam - 84.0-91.7; hydrated lime - 5.0-7.0; gas-cleaning dust from production of ferrous alloys - 1.0-5.0; saponified tall oil fatty acids - 1.8-2.5; brine - 1.8-1.5.
EFFECT: low average density, heat conductivity, air shrinkage of articles and reduced spoilage during drying.
