NANODIAMONDS SYNTHESIS METHOD Russian patent published in 2018 - IPC B01J3/08 C30B29/04 C01B32/26 C01B32/25 B82B3/00 B82Y40/00 B82Y10/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to the synthesis of nanodiamonds for use in optical memory elements for high-performance quantum computers. Method includes preparing a carbon-containing mixture, placing it in a high-pressure chamber, initiating an intensive shock wave in a carbon-containing mixture, filtration and separation of the synthesis products, while a mixture based on the saturated hydrocarbons of the homologous series of alkanes with a general formula C_nH_2n+2 is selected as a carbon-containing mixture with a number of carbon atoms of 16 and above, it is heated to a temperature above 300 K, methane is passed through it at a pressure above 0.1 MPa and a pulsed electric discharge is formed in the carbon-containing mixture.

EFFECT: invention makes it possible to obtain nanodiamonds of high purity, in particular without an admixture of nitrogen, in a size from 3 to 10 nm with improved thermal and electrophysical properties.
