    摘要: A method for producing isolatable oxide microparticles or hydroxide microparticles using an apparatus that processes a fluid between processing surfaces of processing members that are arranged opposite each other so as to be able to approach to or separate from each other and such that at least one can rotate relative to the other. At least two fluids are mixed and oxide microparticles or hydroxide microparticles are separated, said two fluids including: a fluid containing a microparticle raw material solution comprising a microparticle raw material mixed into a solvent, and a fluid containing a microparticle-separation solution. Immediately thereafter, the following are mixed to obtain isolatable oxide microparticles or hydroxide microparticles: a fluid containing the separated oxide microparticles or hydroxide microparticles; and a fluid containing a microparticle-treatment-substance-containing solution that contains a microparticle-treatment substance that adjusts the dispersibility of the separated oxide microparticles or hydroxide microparticles.

    摘要: The present invention is directed to compositions and processes for the production of stable, alkaline, high solids, low viscosity, low surface tension, low flammability, sub-micron titania sols that have minimal offensive odor and methods of their use. Compositions of the present invention include, for example, mixtures of strong and weak organic bases used as dispersants to stabilize the titania sols. The dispersant mixtures have been found to result in relatively high titania solids content, low surface tension, low viscosity suspensions that are low in flammability. Sols produced according to the present invention can be used, for example, in catalytic applications such as catalyst supports for diesel emission control, or in pollutant photocatalyst applications in which it is desirable to have the titania in sol form.

    摘要: A method for producing high-active titanium dioxide anatase hydrosol by using metatitanate as precursor, is characterized in comprising the following steps in order: (1) Wash process: adding alkali to wash so as to remove sulfate ion; (2) Dispersion process: adding acid to disperse the filter cake and obtaining a uniform suspension; (3) Peptization process: peptizing the suspension obtained in dispersion process according to the method of (a), (b) or (c). When producing transition metal or rare earth doped anatase hydrosol, transition metal or rare earth salt solution with a predetermined concentration is first prepared, and then added into the metatitanate suspension which has not been washed by alkali. Subsequently, the resulting suspension is filtered and washed until no sulfate ion is present. When producing precious metal deposited anatase hydrosol, precious metal solution is added into prepared pure anatase hydrosol, and then, the resulting solution is irradiated with ultraviolet light for 0.5-10 hours under stirring continuously. The advantages and beneficial effects of the present invention are as follows: (1) the raw material has low price and little pollution as well as abundant source; (2) the hydrosol has excellent degree of dispersibility and higher anatase crystallization; (3) the hydrosol has higher activity under visible light irradiation owing to doping/depositing technique; (4) the properties and activity of the hydrosol can be further enhanced by using post disposal, such as microwave and ultrasonic technique; and (5) the hydrosol is a kind of nano-material with about 10 nm particle size. The anatase hydrosol can be applied for indoor air purification, crop disease control, odor control and so on.

This material with a large crystal size has unusually high reflection of NIR radiation and, simultaneously, noticeably diminished reflectance of visible light. Also disclosed is a coated particulate TiO2 material, wherein the material has an average crystal size of greater than 0.40 μm, and the coating comprises one or more oxide material; this provides low levels of photocatalytic activity that were previously unattainable. This coated TiO2 material may be provided in a composition.
