Abstract: A method for modifying a fine particle dispersion liquid with which dispersibility and dispersion stability can be improved includes performing filtration to remove impurities in a dispersion liquid using a dispersion liquid modifying device provided with a removal unit that uses a filtration membrane. The quantity of impurities is reduced from a first region until said quantity reaches a second pH-dependent region. In the second pH-dependent region, the dispersibility of the fine particles in the dispersion liquid is in a range in which the dispersibility depends more on a change in dispersion liquid pH than on a change in the quantity of impurities in the dispersion liquid. With the quantity of impurities reduced to the second pH-dependent region, the dispersibility of the fine particles is controlled by adjusting the pH of the fine particle dispersion liquid.

Abstract: The present invention is directed to a method of making metal oxide and mixed metal oxide particles. The method includes treating a mixture formed from a metal source, such as metal alkoxide, a surfactant, and a first alcohol in an aqueous media at a very high metal oxide yield. The mixture is reacted using a catalyst to form metal oxide particles having a desired particle size in said mixture. By washing the particles with an aprotic solvent, the residual carbon content of the particles can be significantly reduced. The method is particularly suitable for forming silica particles. The metal oxide particles can then be heat treated to form synthetic fused metal oxides such as, for example, synthetic fused silica.

Abstract: 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.

Abstract: A method and structure for making magnetite nanoparticle materials by mixing iron salt with alcohol, carboxylic acid and amine in an organic solvent and heating the mixture to 200–360 C is described. The size of the particles can be controlled either by changing the iron salt to acid/amine ratio or by coating small nanoparticles with more iron oxide. Magnetite nanoparticles in the size ranging from 2 nm to 20 nm with a narrow size distribution are obtained with the invention. The invention can be readily extended to other iron oxide based nanoparticle materials, including M Fe2O4 (M=Co, Ni, Cu, Zn, Cr, Ti, Ba, Mg) nanomaterials, and iron oxide coated nanoparticle materials. The invention also leads to the synthesis of iron sulfide based nanoparticle materials by replacing alcohol with thiol in the reaction mixture. The magnetite nanoparticles can be oxidized to γ-Fe2O3, or α-Fe2O3, or can be reduced to bcc-Fe nanoparticles, while iron oxide based materials can be used to make binary iron based metallic nanoparticles, such as CoFe, NiFe, and FeCoSmx nanoparticles.
