摘要： A surface-fluorinated metal oxide particulate comprising a metal oxide particulate selected from titanium, aluminum, silicon, silver, copper, zirconium, zinc, tin, germanium, tantalum and the like, being reacted with fluorine and a process for manufacturing such surface-treated metal oxide particulates are disclosed. The process allows easy and efficient fluorination of the surface of metal oxide particulates in any desired ratio. The surface-fluorinated metal oxide particulates of the present invention are useful as an additive for weatherable paints, weatherable resins, cosmetics and the like. Surface-fluorinated titanium oxide particulates obtained by fluorination of titanium oxide particulates have improved light stability, water-repellence, and dispersibility as compared with conventional titanium oxide particulates and maintains surface smoothness of the resin-coated substrate when contained in high concentrations in thermoplastic resins as a white pigment with water content being controlled in a specified range and prevents the occurrence of troubles at the time of melt extrusion coating for obtaining resin-coated substrates.

摘要： A photocatalytic titanium dioxide powder comprised of finely divided titanium dioxide particles each having supported on the surface thereof a first supported layer of a calcium compound and further having on the surface of the first supported layer-formed particles a porous second supported layer of a photocatalytically inactive and substantially water-insoluble substance. The photocatalytic titanium dioxide powder is produced by allowing a calcium compound to be supported on the surface of finely divided titanium dioxide particles to form the first supported layer; and then, allowing a precursor material capable of forming the photocatalytically inactive and substantially water-insoluble substance to be supported on the surface of the first supported layer-formed particles, followed by converting the precursor a material to said water-insoluble substance to thereby form the porous second supported layer. A composition comprising a polymer and the photocatalytic titanium dioxide powder is used as a shaping material or a coating material for the fabrication of a shaped article or structure for environmental purification.

摘要： A condensed phosphate containing an alkaline earth metal is caused to be present on the surface of titanium dioxide fine particles, and as a result, the condensed phosphate is firmly coupled with the fine particles and is barely liberated from the surface of the fine particles into a medium such as a binder or a resin. As a result, photo-functional particles exhibiting durability and dispersion stability are obtained. By use of the photo-functional particles, a powder and a slurry exhibiting excellent photo-functional property, durability, dispersion stability, and hydrophilicity are produced. In addition, by use of the powder and slurry, a polymer composition, a coating agent, a photo-functional formed article, and a photo-functional structure are produced.
