Abstract

FIELD: production of artificial diamonds. SUBSTANCE: carbon- containing material of a specified shape is surrounded with a powdered catalyst containing, %: 60-70 tungsten carbide, 10-12 titanium carbide, 2.4-2.6 cobalt, 2.4-2.6 titanium boride and 15-21 zirconium, and high pressure and temperature are then applied, the velocity of the temperature rise being 1400-1600 deg/s. The material is kept at high temperature for 1-2 s, and its subsequent treatment with a mixture of nitric acid and HF is carried out at room temperature. EFFECT: new method elaborated.

Изобретение относится к области производства искусственных алмазов, в частности к получению поликристаллических алмазов заданной формы. Способ заключается в том, что углеродсодержащий материал заданной формы окружают порошкообразным катализатором, содержащим карбид вольфрама, карбид титана, кобальт, борид титана и цирконий, и воздействуют высокими давлением и температурой. Новым в способе являются дополнительно взятые в качестве катализатора порошки борида титана и циркония при соотношении компонентов, мас.%: карбид вольфрама 60 - 70; карбид титана 10 - 12; кобальт 2,4-2,6; борид титана 2,4-2,6; цирконий 15 - 21. Скорость повышения температуры 1400-1600 град/с. Выдержка 1-2 с и последующая химическая обработка смесью кислот НNO3 и HF при комнатной температуре.The invention relates to the field of production of artificial diamonds, in particular to the production of polycrystalline diamonds of a given shape. The method consists in the fact that a carbon-containing material of a given shape is surrounded by a powdery catalyst containing tungsten carbide, titanium carbide, cobalt, titanium boride and zirconium, and is exposed to high pressure and temperature. New in the method are additionally taken as a catalyst, powders of titanium boride and zirconium with a ratio of components, wt.%: Tungsten carbide 60 - 70; titanium carbide 10-12; cobalt 2.4-2.6; titanium boride 2.4-2.6; zirconium 15 - 21. The rate of temperature increase is 1400-1600 degrees / s. Exposure 1-2 s and subsequent chemical treatment with a mixture of acids НNO 3 and HF at room temperature.
