Patent number: 6602918Abstract: The invention provides a process of producing a titanium oxide-forming solution, wherein a hydrogen peroxide solution is added to a titanium-containing starting aqueous solution to form a peroxotitanium complex, a basic substance is then added to the peroxotitanium complex to obtain a solution which is in turn let stand or heated, thereby forming a precipitate of a peroxotitanium hydrate polymer, at least a dissolved component derived from the titanium-containing starting aqueous solution, except water, is then removed from the precipitate, and a hydroxide peroxide solution is finally allowed to act on a dissolved component-free precipitate. The invention also provides a dispersion with titanium oxide dispersed therein.Type: GrantFiled: February 24, 2000Date of Patent: August 5, 2003Assignee: Saga PrefectureInventor: Hiromichi Ichinose

Publication number: 20030082367Abstract: The present invention is directed to a process for obtaining a substrate provided with a coating having photocatalytic properties, wherein the coating includes crystallized particles of an oxide of a metal A having photocatalytic properties. The crystallized particles are incorporated into the coating using a mineral binder comprising at least one oxide of a metal B also having photocatalytic properties in the crystallized state. The coating optionally includes at least oxide of a metal M devoid of photocatalytic properties and/or at least one silicon compound of the silicon oxide SiO2 type. The coating is deposited from liquid-phase dispersions containing the crystallized particles of the oxide of metal A and at least one precursor compound for the oxide of metal B of the binder and optionally a precursor compound for the oxide of metal M and for the Si compound, in a relative proportion A/(B+M+Si) by weight of the metals and Si ranging between 60/40 and 40/60.Type: ApplicationFiled: September 5, 2002Publication date: May 1, 2003Applicant: Saint-Gobain VitrageInventors: Xavier Talpaert, Michel Simonet, Corinne Lehaut, Thierry Chopin, Frederic Magnin-Feysot

Patent number: 6500249Abstract: Stains and methods of forming stains comprising saturated hydrochloric acid solutions of blended metallic salts that are chemically reactive with masonry concrete, stone, and like materials. The concentrated stains produce a full spectrum of colors derived from earth elements in the metals and transition element group, and from ores, and refined chemicals. Groups of concentrated mixtures emphasize the colors black, yellow, cyan and magenta to produce an overall earth-tone color. By separately dissolving each heavy metal constituent in an acid solution to the point of total saturation or crystallization, and then adding these mixtures to a predetermined base acid mixture, a stable, concentrated stain results. The individual ingredients are blended to produce a chosen color spectrum by adjusting mixture proportions.Type: GrantFiled: May 9, 2000Date of Patent: December 31, 2002Inventor: Marvin T. Dodson
