CHEMICAL METHOD OF PRODUCING ARTIFICIAL DIAMONDS Russian patent published in 2016 - IPC B01J3/00 C30B29/04 C01B31/06 B82B3/00 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: invention relates to inorganic synthesis of artificial diamonds of size of up to 150 mcm, which can be used in production of abrasive and diamond lubricants, drilling equipment. Synthesis of diamonds is carried out in molten metal matrix with direct reaction of carbon-containing additive contained in concentrations of 2 to 10 wt% in molten chlorides and/or fluorides of alkali metals, with molten metal, such as aluminium, zinc, magnesium, tin, lead, as well as their alloys for 1-5 hours at temperature of 700-900 °C in an air atmosphere and further cooling and/or thermal treatment, carbon-containing additive is represented by carbides of metals or non-metals or solid organic substances relating to classes of hydrocarbons or carbohydrates, or carboxylic acids.

EFFECT: invention enables to obtain cubic nano- and micro-diamond at atmospheric pressure and low temperature without using complex processing equipment.
