FINELY PARTICULATE TITANIUM-CONTAINING SUBSTANCE, COATING FLUID CONTAINING THE SAME, PROCESSES FOR PRODUCING THESE, AND MOLDED ARTICLE HAVING THIN FILM COMPRISING THE SUBSTANCE |
摘要 |
<p>A titanium-containing finely divided particulate material, characterized by exhibiting a light transmittance of at least 85% as measured at a wavelength of 450-700 nm for a thickness of 10 mm on an aqueous liquid containing the titanium-containing material in a concentration of 0.1 to 6.5 moles per liter as titanium even when the temperature of the liquid is elevated to the boiling point. The titanium-containing material usually has an average particle diameter of 0.8-50 nm, and gives a film having high photocatalytic activity and transparency. The titanium-containing finely divided particulate material is obtained by hydrolyzing titanium tetrachloride in an aqueous solution in the presence of a carboxylic acid. <IMAGE></p> |
