Diamond micropowder refers to diamond particles with a particle size less than 36/54 microns, including single crystal diamond micropowder and polycrystalline diamond micropowder. Single crystal diamond micro-powder is made of artificial diamond single crystal abrasive particles, which are crushed and shaped and made by special technology. Diamond micropowder has high hardness and good wear resistance, and can be widely used in cutting, grinding and drilling. It is an ideal raw material for grinding and polishing high hardness materials such as cemented carbide, ceramics, precious stones and optical glass. Diamond micropowder products are tools and parts made of diamond micropowder. Polycrystalline diamond micropowder is made of graphite by a unique directional blasting method. The shock wave of directional blasting of high-energy explosives makes the metal flyer fly faster and hit the graphite flake, which leads to the transformation of graphite into polycrystalline diamond. Its structure is very similar to natural diamond, which is formed by unsaturated bonds and has good toughness.
