| description | A method for manufacturing an inexpensive and safe titanium dioxide powder having an excellent photocatalytic ability and a high purity of anatase phase crystalline structure by utilizing meta-titanic acid as a starting material is disclosed. Meta-titanic acid is first neutralized by a basic solution, followed by adding a metal oxide. Then, the meta-titanic acid is spray dried using hot air to obtain spherical shape granules. The granules are then sintered to obtain the resulting titanium dioxide powder having small sized porous second particles and a high specific surface area. As a result, an economical and highly effective photocatalytic titanium dioxide powder can be obtained. |
