FIELD: chemistry.
SUBSTANCE: ions of carbon with opposite charges interact with each other for 20-30 hours at a temperature of 850-950 °C in a high frequency electro-field in the range of frequencies of 40-80 kHz in the presence of iron as a catalyst. The process is carried out in a melt of salts, containing, wt %: SiC - 7.5-11.0; Na2CO3 or K2CO3 - 89.0-92.5. Applied is granulated iron, which has a size of granules 1-3 mm, in a quantity of 5-10% from the melt weight.
EFFECT: invention makes it possible to simplify the process of the diamond synthesis and its instrumentation, eliminate harmful and dangerous conditions.
