DECOMPOSITION PROCESS FOR PRODUCING SUBMICRON PARTICLES IN LIQUID BATH Russian patent published in 2005 - IPC

FIELD: production of submicron powders of pure metals and of metal compounds in bath with liquid.

SUBSTANCE: method for preparing liquid dispersion including metal-containing submicron particles comprises steps of creating bath with selected liquid in reactor; preparing mixture having metal- containing fluid capable at predetermined condition to be decomposed in selected liquid for forming metal-containing submicron particles; introducing prepared mixture to bath with selected liquid; providing in bath condition suitable for decomposition at least of some part of metal-containing liquid in selected liquid for forming metal-containing submicron particles dispersed in selected liquid. According to invention mixture including metal-containing fluid is added by bubbling into bath with selected liquid in the form of mixture formed by mixing metal-containing fluid with inert carrier gas.

EFFECT: possibility for realizing continuous process of improved economical effectiveness.
