FIELD: production of artificial crystals of diamond. SUBSTANCE: it is known that in powerful enough electric arc between carbon electrodes placed in compressed (about 20 atm) hydrogen medium, electrode material melts and is converted into liquid melt of carbon which in a short period of time evaporates to convert into typical graphite. Plant allows for a fraction of a second without time for liquid evaporation, withdrawal of melt by vortex of flow of compressed gas from electric arc and transportation it into liquid coolant where melt is intensively cooled to crystallize into diamond. This is attained due to the fact that ends of carbon-containing electrodes are immersed into throat of outlet channel from gastight chamber. Channel is closed by slide valve. When slide valve opens and lower electrode turns, the way for carbon melt to liquid coolant is opened. EFFECT: higher efficiency. 4 cl, 2 dwg
