MECHANOCHEMICAL CRUSHING OF DIAMONDS Russian patent published in 2011 - IPC B02C23/06 B82B3/00

Abstract RU 2415717 C1

FIELD: process engineering.

SUBSTANCE: invention relates to production of nano-sized diamonds. Proposed method comprises crushing diamonds in mill, chemical treatment, removal of supernatant fluid, rinsing produced nano diamonds and their drying. Prior to crushing, initial diamonds are mixed with ground ballast high-hardness substance. Crushing is carried out in vibration mill. Chemical treatment is performed in acid to dissolve particles of said ballast substances and other impurities originating in crushing.

EFFECT: reduced amorphicity of surface layers of produced nano diamonds.
