| 20100326323 | SURFACE-MODIFIED TITANIUM DIOXIDE PARTICLE AND METHOD FOR PRODUCING THE SAME - The invention provides a surface-modified titanium dioxide particle inhibited in photocatalytic activity and reduced in amount of volatile water. The surface-modified titanium dioxide particle has on the surface a crystalline composite compound of at least one of alkaline earth metals selected from magnesium, calcium, barium and strontium complexed with titanium dioxide in an amount of 0.1-20% by weight based on the weight of the surface-modified titanium dioxide particle in terms of oxide of the alkaline earth metal. The surface-modified titanium dioxide particle is produced by heating a compound of an alkaline earth metal and a titanium dioxide particle at a temperature of 60° C. or higher so that the alkaline earth metal is complexed with titanium dioxide to form a crystalline composite compound on the surface of the titanium dioxide particle in an amount of 0.1-20% by weight based on the weight of the surface-modified titanium dioxide particle in terms of oxide of the alkaline earth metal. | 12-30-2010 |
| 20110253012 | TITANIA COMPOSITE AND PREPARING METHOD THEREOF - A titania composite and a preparing method thereof are provided. The titania composite comprises an inner core and a coating film layer, wherein the inner core is a barium sulfate crystal and/or a strontitum sulfate crystal with subsphaeroidal shape, having a particle size of less than 1 μm and whiteness of more than 98%, and the coating film layer is nano rutile titania. The preparing method thereof comprises the following steps: (a) preparing barium sulfate or strontium sulfate; (b) coating treatment; (c) subjecting the titania composite to a high-temperature heat treatment; and (d) subjecting the titania composite to a post treatment. The subsphaeroidal titania composite is obtained by chemically synthesizing a subsphaeroidal submicron barium sulfide or strontium sulfide, and then hydrolyzing and coating thereon to form a coating film layer of titania to make titania grow evenly. The particle size of the titania composite is small, and the particle size distribution range of the titania composite is controllable. | 10-20-2011 |
