Abstract

Reivindicacion 1: Un método para preparar partículas de oxidos metálicos coloidales, el cual comprende el paso de: (a) agregar oxido metálico reactivo a un recipiente de reaccion a un índice de adicion en masa de oxidos metálicos que está basado en un modelo matemático que tiene en cuenta (i) un índice de nucleacion de partículas, (ii) una velocidad de deposicion de oxidos metálicos sobre las partículas de oxidos metálicos existentes, y (iii) el desarrollo de partículas de oxidos metálicos en el recipiente de reaccion, en el cual el índice de adicion en masa de oxidos metálicos aumenta en funcion del tiempo de reaccion.Claim 1: A method for preparing colloidal metal oxide particles, which comprises the step of: (a) adding reactive metal oxide to a reaction vessel at a mass addition rate of metal oxides that is based on a mathematical model that takes into account (i) a particle nucleation index, (ii) a rate of deposition of metal oxides on existing metal oxide particles, and (iii) the development of metal oxide particles in the reaction vessel, in the which mass addition rate of metal oxides increases as a function of reaction time.
