摘要:
A food container on which surface titanium oxide particles are fixed, where titanium oxide particles may contain brookite crystals, the material of which the food container is constructed may be stainless steel, and the titanium oxide particles may be bonded using a sintering aid, a binder or both. When the food container is made of glass, satisfactory mechanical strength of the container can be maintained even when the thickness of a wall of the container is reduced. Since titanium oxide particles can be fixed onto a surface of a food container at a temperature as low as 20 to 450° C. by use of a sintering aid, a binder or both thermal deformation of glass forming the food container can be prevented.

An object of the present invention is to provide a transparent noise-barrier wall which is slow to foul, easy to clean even when fouled, and capable of maintaining these effects over a long period of time. The transparent noise-barrier wall has brookite titanium dioxide substantially existing on the surface. The titanium dioxide particles preferably contain about 20% by mass or more of brookite titanium dioxide.

A composition comprising metal oxide particles having photo-catalytic activity, a solvent-soluble zirconium compound and a solvent. Preferably, the metal oxide particles having photocatalytic activity are titanium oxide particles; the metal oxide particles have an average particle diameter of about 0.005 to 0.3 &mgr;m; and the amount of the zirconium compound is in the range of about 3-200 parts by weight, as ZrO2, per 100 parts by weight of the metal oxide articles. A composite of a film having a photo-catalytic activity with a base material is made by coating the base material with the above composition to form a film, and curing the film on the base material.

A substrate for use in a perpendicular magnetic recording medium includes a blank substrate and a film of phosphorus- or boron-containing cobalt alloy formed on the blank substrate by electroless plating, the electroless plated film of the cobalt alloy having surface roughness Ra in the range of 0.05 nm to 1 nm. A method for the production of a substrate for use in a perpendicular magnetic recording medium includes a step of forming on a blank substrate a film of phosphorus-containing cobalt alloy by electroless plating and a step of polishing a surface resulting from the step of forming the film by the plating.
摘要:
An aqueous dispersion of titanium oxide particles comprising chloride ion, and a Brønsted base other than chloride ion, preferably at least one kind of ion selected from nitrate ion and phosphate ion. Preferably the titanium oxide particles are predominantly comprised of brookite titanium oxide particles. The aqueous titanium oxide dispersion is prepared by hydrolyzed titanium tetrachloride in the presence of at least one kind of a Brønsted acid. A thin film formed from this aqueous titanium oxide dispersion exhibits good photo-catalytic activity, transparency and adhesion to a base material.
