FIELD: physicochemical methods. SUBSTANCE: microgels are prepared from water-soluble silicate and alkali metal aluminate, which are mixed with velocity ensuring Reynolds number at least 4000, after which mixture is aged and the diluted to silicon oxide concentration no higher than 1.0 wt.%. EFFECT: reduced precipitation of silicon dioxide during microgel preparation. 6 cl, 4 dwg, 2 tbl, 4 ex |
