Silicon dioxide sol and method of its producing |
| abstract |
FIELD: inorganic chemistry. SUBSTANCE: product: silicon dioxide sol of specific surface 750-1000 m 3 /g at microgel content 8-45 wt.-% and modification degree with aluminium - 2-25%. Sol is obtained by acidification of water glass solution to pH = 1-4 followed by alkalinization up to SiO 2 content 4.5-7 wt.-%, ripening and modification with aluminium up to modification degree 2-25%. Proposed sol is used for paper production. EFFECT: improved method of sol producing. 19 ex, 3 cl, 6 tbl |
