METHOD FOR MANUFACTURING ISOLATABLE OXIDE MICROPARTICLES OR HYDROXIDE MICROPARTICLES

WIPO Patent Application WO/2012/026579

A1

A method for manufacturing isolatable oxide microparticles or hydroxide microparticles using a device that processes a fluid between processing surfaces of processing units that are arranged opposite each other so as to be able to move closer to or farther apart from each other and such that at least one can rotate relative to the other. Using a device that processes a fluid between processing surfaces (1 and 2) of processing units (10 and 20) that are arranged opposite each other so as to be able to move closer to or farther apart 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 precipitated out, said two fluids including: a fluid containing a microparticle feedstock solution comprising a microparticle feedstock mixed into a solvent; and a fluid containing a microparticle-precipitation liquid. Immediately thereafter, the following are mixed to obtain isolatable oxide microparticles or hydroxide microparticles: a fluid containing the precipitated oxide microparticles or hydroxide microparticles; and a fluid containing a microparticle-treatment-substance-containing solution that contains a microparticle-treatment substance that adjusts the dispersivity of the precipitated oxide microparticles or hydroxide microparticles.
