FIELD: chemical technology. SUBSTANCE: gibbsite is subjected for mechanical-chemical activation following by plasticization in the presence of mineral acid and addition of aluminium hydroxide at concentration 0.5-7.0 wt. -% (as aluminium oxide of mixture mass). Product after plasticization is used as aluminium hydroxide addition. Method ensures to increase specific surface of aluminium oxide from 38 to 260 - 300 m/g, filled density from 0.48 to 0.53-0.58 g/cmand strength up to 1.4-1.7 kg/mm. EFFECT: enhanced quality of product. 2 cl, 1 tbl
