Abstract | methods of cleaning of synthetic ultradispersed diamonds in withdrawal of diamonds from product of detonation synthesis. SUBSTANCE: 100 g of diamond mixture containing about 40 wt.% of diamonds and the rest in form of nondiamond carbon and metal impurities are placed on pan of electric furnace. Mixture is heated up to 380-440 C at rate of 2.5-10 C/min and held at maximum temperature for 2-4 h. Diamond yield amounts to 38.5-39.1 wt.%, content of nondiamond carbon is 0.1-0.8 wt.%. EFFECT: simple method with use of no toxic media. 2 ex |
