METHOD FOR GROWING NOBLE METAL MONOCRYSTALS OR ITS NANO- AND/OR MICROSALT Russian patent published in 2009 - IPC C30B7/14 B82B3/00

Abstract RU 2358042 C2

FIELD: chemistry.

SUBSTANCE: method involves chemical reduction of noble metal ions from an aqueous solution of its compound with a reducing agent being anionic polyelectrolyte and noble metal ions concentrated 0.1-5 mg-ion/dm³ and polyelectrolyte concentrated 5-350 mg/dm³. The process is intensified due to temperature rise within 20-60°C and/or light exposure 500-3000 lux.

EFFECT: invention allows for nano- and micro- monocrystals in free liquid volume without sol particle impurity while maintaining the size within specified range.
