| titleOfInvention | Alumina powder |
| abstract | The alumina powder according to the present invention contains a hydroxycarboxylic acid and an alkali component, the crystal structure of the alumina is amorphous, pseudoboehmite or boehmite, and all of the following (1) to (4) Have. (1) When the alumina powder and distilled water are mixed so as to be 2.5% by mass as Al 2 O 3 , a colloidal dispersion (A) is obtained without causing precipitation, and the colloidal dispersion ( When A) is measured under the conditions of a wavelength of 500 nm and an optical path length of 10 mm, the light transmittance is 80% or more. (2) When the alumina powder and distilled water are mixed so as to be 15% by mass as Al 2 O 3 , the colloidal dispersion (B) is obtained without causing precipitation. (3) The pH range of the colloidal dispersion (A) and the colloidal dispersion (B) is 5-8. (4) When the alumina powder and methanol are mixed so as to be 2.5% by mass as Al 2 O 3 , a colloidal dispersion (C) is obtained without causing precipitation, and the colloidal dispersion (C ) Is 80% or more when measured under the above conditions. |
