| 20090143498 | PROCESS FOR PREPARING DISPERSED INGEDIENT HAVING METAL-OXYGEN BONDS - A dispersed ingredient having metal-oxygen bonds which is obtained by hydrolyzing a metal alkoxide in an organic solvent in the absence of an acid, a base, and/or a dispersion stabilizer, either with 0.5 to less than 1 mol of water per mol of the metal alkoxide or at −20° C. or lower with 1.0 to less than 2.0 mol of water per mol of the metal alkoxide. In the organic solvent, the dispersed ingredient is stably dispersed without aggregating. Use of the dispersed ingredient enables a thin metal oxide film and a homogeneous organic/inorganic composite to be produced at a temperature as low as 200° C. or below. | 06-04-2009 |
