The foundation of diamond powder is briefly introduced

The diamond powder we say refers to diamond particles with a particle size finer than 60 microns, which is a very fine particle, the thickness of a hair of our normal people is also 70 microns, so the diamond powder is finer than our hair, our existing diamond powder has single crystal diamond powder and polycrystalline diamond powder. After the rapid development of modern nanotechnology is also the same rapid development, in the original two categories of diamond powder and out of a new product that is: nano-diamond powder. The following small series introduces the characteristics of these diamond powder

Single crystal diamond powder:

Monocrystalline diamond micropowder is produced by artificial monocrystalline diamond abrasive particle, which is crushed and shaped by special process method of superhard material. Diamond powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, polishing and so on. It is the ideal raw material for grinding and polishing hard alloy, ceramics, gems, optical glass and other high hardness materials. Diamond powder products are tools and components made of diamond powder processing.

Polycrystalline diamond powder:

Polycrystalline diamond micropowder is made from graphite by a unique directional blasting method. The shock wave of high explosive speed directional blasting accelerates the flight of the metal flying sheet and impacts the graphite sheet, resulting in the conversion of graphite into polycrystalline diamond. Its structure is very similar to natural diamond, which is combined by unsaturated bonds and has good toughness.

Nano-diamond powder:

Nanotechnology is a new technology after the rise of the 1990s, nanoscale diamond by the size of the nanoscale, that is, one billionth of a meter of diamond particles, is a new material synthesized by explosive technology in recent years. It not only has the inherent characteristics of diamond, but also has small size effect, large specific surface area effect, quantum size effect, etc., so it shows the characteristics of nanomaterials. The diamond synthesized in detonation waves has a cubic structure, a lattice constant of (0.3562+0.0003) nm, a crystal density of 3.1g/cm³, and a specific surface area of 300m² / g~390m² / g. After treatment with different chemical methods, a variety of different functional groups can be formed on the diamond surface, and this diamond crystal has a high adsorption capacity.
