FIELD: chemistry. ^ SUBSTANCE: composition includes magnesium hydroxoaluminate and aluminium hydroxide with crystal size of 1-100 nm at the following component ratio, wt %: magnesium hydroxoaluminate 10.00-99.99, aluminium hydroxide 0.01-90.00. To obtain the claimed composition, sodium aluminate and magnesium chloride solutions, or aluminium nitrate and magnesium nitrate solutions, or aluminium chloride and magnesium chloride solutions are mixed, alkaline reactant is added to the mix, S:L of 1:5-10 and medium pH of 7.0-7.8 are achieved, sediment is filtered, flushed and dried to achieve constant weight. ^ EFFECT: obtainment of composition applicable as raw material in antacid production and in ceramic and fireproof material production. ^ 2 cl, 1 dwg, 3 ex |
