METHOD FOR PRODUCTION OF ULTRA-DISPERSED DIAMONDS AND INSTALLATION FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC C01B32/25 B01J3/08 B82B3/00 B82Y40/00 C30B29/04 

FIELD: mining; chemistry; tool industry; instrument making.

SUBSTANCE: invention relates to the field of mining, chemistry, tool industry, as well as instrument making, in particular to synthesis of ultra-dispersed diamonds, which can be used in quantum physics, biology, materials science, microelectronics, and medical diagnostics in the creation of different nano-composites, catalysts, anti-wear additives to oils, etc. A method for the production of ultra-dispersed diamonds is proposed, including obtainment of working carbon-containing liquid, its supply to a jet cavitation device of a hydrodynamic type, impact-wave loading in a closed system without the use of protective atmosphere, and subsequent isolation from recycled working liquid of a final product. The method differs in that obtained working liquid is divided into two parallel streams, and they are supplied at a speed of 5-11 m/s, the first stream is directed through the cavitation device, impact-wave loading is carried out with a quick-lock pneumatic valve located after the device and triggering in an interval of 10-60 sec with a hydraulic impact equal to 1-3 MPa, back pressure of 0.1-0.5 MPa is established in the second stream, working liquid is a mixture of distilled water and water-soluble hydrocarbon liquids, as which methanol, ethanol, and isopropyl alcohol are used in amount of 3-20%. An installation for the implementation of the specified method is also proposed.

EFFECT: proposed method allows for provision of effective synthesis of ultra-dispersed diamonds on an industrial scale.
