| titleOfInvention | Method for producing titanium hydroxide |
| abstract | The subject of the present invention is to provide a method for producing fine and high-purity titanium hydroxide, which can maintain a high ratio of 90 m 2 / g or more even when heated to 600 ° C. in the production of barium titanate, for example. Surface area.n n n The invention provides a method for manufacturing titanium hydroxide, comprising: Step A, under conditions of pH 4.8 to 5.2 and temperature 40 to 55 ° C, simultaneously neutralizing a titanium halide aqueous solution and an alkaline substance to obtain a BET specific surface area Titanium hydroxide having a diameter of 300 m 2 / g or more and a crystallite diameter of 20 Å or more; and step C, after washing the above titanium hydroxide with water, dispersing it in water to obtain a slurry containing the above titanium hydroxide, and the following ( a) or (b), a phosphorus compound and / or a silicon compound are added to the slurry, and the obtained mixed slurry is washed with water and dried; (a) the titanium hydroxide is titanium oxide (TiO 2 ) Converted to a phosphorus compound of 1.0 to 5.0% by weight or a silicon compound of 2.0 to 5.0% by weight, (b) a total amount of 1.0 to 5.0% by weight or less of phosphorus relative to the above-mentioned titanium hydroxide in terms of titanium oxide (TiO 2 ). Compounds and silicon compounds. |
