FIELD: chemical technology of inorganic compounds. SUBSTANCE: method involves preparing silica gel suspension (aluminium fluoride production waste) with solution of sodium hydroxide at the mole ratio of the parental components (as oxides) SiO2:Na2O:Al2O3= 1:(0,8-1,5):(0,1-0,18) 1:(0.8-1.5): (0.1-0.18). Mixture is heated up to the boiling point and kept at this temperature and stirring for 1.0-2.5 h. Product is used for producing low-siliceous zeolites, synthetic detergents. EFFECT: improved method of producing.
