Abstract
PURPOSE: To obtain an alumina sol having superior stability on standing and a desired viscosity and capable of giving alumina powder with superior redispersibility by neutralizing an acidic water sol. aluminum salt with alkali followed by hydrothermal treatment in the presence of a water sol. aluminum salt of a monovalent org. acid.
CONSTITUTION: An acidic water sol. aluminum normal salt, e.g. aluminum chloride or aluminum nitrate, or a sol. basic aluminum salt of a monovalent org. acid, e.g. aluminum acetate is neutralized with an alkaline substance at 5W50°C to obtain an alumina gel. The alkaline substance includes hydroxides, carbonates, bicarbonates, sulfites and borates of alkali (earth) metals and ammonia. After drying the resulting gel to an Al2O3 content of 15W90, pref. 55W80% a monovalent org. acid or a water sol. aluminum salt thereof, e.g. aluminum acetate is added in an amt. required to adjust the molar ratio of acid residue/Al to 0.001W0.12, pref. 0.002W 0.10, followed by hydrothermal treatment at 140W200°C for 30minW4hr. Thus, an alumina sol is produced.
