The Structural Composition of Diamond Powder

Diamond powder refers to diamond particles with particle size smaller than 36 / 54 μ m, including single crystal diamond dust and polycrystalline diamond dust. Due to the large production and wide application of single crystal diamond dust, diamond powder suppliers generally refer to diamond dust as single crystal diamond dust. Single crystal diamond dust is made of synthetic diamond single crystal abrasive particles by static pressure method, which are crushed and shaped, and produced with a special process of super hard materials. Diamond dust with high hardness and good wear resistance can be widely used in cutting, grinding, drilling, polishing, etc. It is an ideal raw material for grinding and polishing hard alloy, ceramics, gemstone, optical glass and other high hardness materials. Diamond dust products are tools and components made of diamond dust.

Polycrystalline diamond powder is made of graphite by a unique directional blasting method. The shock wave of directional blasting of high explosive speed accelerates the flying speed of metal flyer and impacts the graphite flake, resulting in the transformation of graphite into polycrystalline diamond. Its structure is very similar to that of the natural Carbonado diamond. Its particles are composed of tiny diamond grains which are combined by unsaturated bond and have good toughness. However, due to the limitation of synthesis conditions, there are few diamond powder suppliers and high product cost. At the same time, the particle size that can be provided in batches is not more than 10 microns, which limits its application field.
