FIELD: chemistry.SUBSTANCE: invention relates to production of synthetic diamonds and can be used as nuclear radiation detectors in fast particle counters, as well as in jewelry. Method involves depositing carbon on seed crystals of diamonds during their heating in vacuum, seed crystals pre-fixed on surface of a polished monocrystalline silicon plates coated with a layer of polyvinyl acetate, after which silicon plate is heated with electric potential shift 80 in vacuum, then methane is supplied at pressure 10-30 Torr and curing at a temperature of 1,170±20 °C with cyclic pumping of reaction products and feed fresh methane.EFFECT: technical result consists in significant increase of initial diamond crystals in group process over a considerably shorter process cycle.1 cl, 2 dwg, 1 ex |
