SUBSTANCE ON BASIS OF MAGNESIUM HYDROXOALUMINATE, CONTAINING COPRECIPITATED ALUMINIUM HYDROXIDE, AND WAY OF ITS OBTAINING Russian patent published in 2009 - IPC C01F7/16 

FIELD: medicine.

SUBSTANCE: inventions concern areas of pharmaceutical and nonferrous metallurgy and can be used for reception of magnesium hydroxoaluminate. The substance contains magnesium hydroxoaluminate Mg₆Al₂ (OH) ₁₈ (4-4.5) H₂O 10-99.99 wt % and coprecipitated aluminium hydroxide 0.01-90.0 wt %. The substance is obtained as follows. The solution containing 26.241-88.262 kg of sodium aluminate in recalculation on aluminium hydroxide, and the solution containing 2.485-24.848 kg of magnesium salt in recalculation on magnesium oxide is taken; the first half of solution of sodium aluminate joins a solution of magnesium salt within 12-25 minutes, then second half of solution of sodium aluminate joins during 35-45 minutes and the suspension pH value is established about 8-9, the received deposit is mixed up, filtered, washed and dried to constant weight.

EFFECT: invention allows framing substance which can be used for manufacture of an antiacid agent and agglutinating additive in ceramic manufacture.
