FIELD: chemistry.
SUBSTANCE: invention relates to the industry of ceramic materials, primarily to compositions of mixtures for making brick. The ceramic mixture for making ceramic brick contains low-melting clay and aluminium-containing sludge from caustic etching with the following content of oxides, wt %: SiO2 - 1.5-2; Al2O3 - 85-90; Fe2O3 - 2.5-3.0; CaO - 2-2.5; MgO - 1-1.5; R2O - 0.8-1.5, with the following ratio of components, wt %: low-melting clay - 70-90; aluminium-containing sludge from caustic etching - 10-30.
EFFECT: high frost-resistance, compression strength and heat-resistance of articles.
