Diamond powder production situation

1.1 monocrystalline diamond powder: 1) the use of static single-crystal diamond type Ⅰ or Ⅱ type material production, mostly for metal type. 2) a special powder synthesis process can be metal or resin-bound-bound. 3) low-grade synthetic processes, such as 8 minutes and crafts. Domestic synthetic diamond of single crystal diamond: 40-50 one hundred million kt / year, ranking first in the world production of domestic monocrystalline diamond powder: 4-5 one hundred million kt / year (except for crushing material). 1.2 PCD (polycrystalline) diamond powder: the use of explosives and move the heat generated by high pressure, the graphite into Polycrystalline diamond. Domestic production capacity: about 2000-4000 ten thousand kt / year. 1.3 detonation nanodiamonds: negative cutting tools in explosive under conditions of free carbon produced, under certain conditions to form nano-diamond powder. Domestic and foreign production: 1000-2000 ten thousand kt / year production capacity is very high.
