実験手順
Aluminum dodecyloxide was prepared in the same manner as in Example 1. Then a part of the aluminum dodecyloxide was hydrolyzed in the same manner as in Example 1 to obtain an alumina slurry. A remained part of aluminum dodecyloxide was mixed with isopropyltitanium (produced by Kishida Kagaku K.K.) at a mixing ratio of 100:5 by weight. The mixture was hydrolysed in the same manner as in Example 1 employing the above alumina slurry as a crystal seed to obtain a titanium dioxide-containing alumina slurry. This alumina slurry was diluted with water to a solid alumina hydrate content 7.9%. The alumina slurry showed pH of 9.5. The pH was adjusted by adding a 3.9% nitric acid solution to a pH before aging as shown in Table 1. The alumina slurry was aged under the conditions shown in Table 1 to obtain a colloidal sol of alumina hydrate. This colloidal sol was spray-dried in the same manner as in Example 1 to obtain alumina hydrate, which had a boehmite structure, and was in a form of a plate-shaped particles as same as in Example 1. Properties of the alumna hydrate were measured as described above. The measured properties are shown in Table 1. The titanium dioxide was contained only at and near surface of the alumina hydrate particles.
