What is Diamond Micron Powder?
Diamond micron powder is mainly divided into three types: single crystal diamond micron powder, polycrystalline diamond micron powder and nano diamond micron powder.
Single crystal diamond micron powder is made of artificial diamond single crystal abrasive grains by crushing, shaping and special process.
Polycrystalline diamond micron powder is prepared from graphite through a unique directional blasting method. The shock wave of the high-explosive directional blasting can accelerate the flight of the metal fly and hit the graphite sheet, thereby transforming the graphite into polycrystalline diamond particles. Although its structure is very similar to natural Kabonado diamond, polycrystalline diamond particles are composed of tiny diamond particles combined by unsaturated bonds, and have good toughness and are mostly used for polishing precision equipment.
Diamond micropowder has high hardness and good wear resistance, and can be widely used for cutting, grinding, drilling, etc. It is an ideal raw material for grinding and polishing hard alloys, ceramics, gemstones, optical glass and other hard materials. Diamond micro-powder products are tools and parts made of diamond micro-powder.
Diamond powder is classified into micron, submicron and nanoscale powders according to particle size. Compared with coarse powder, the specific surface area and surface functional groups of coarse powder are significantly increased, so the interaction between particles during the production process is greatly increased. In addition, as the grain size is refined, the defects of the particles themselves decrease, and the strength inevitably increases. It can be seen that the production process of diamond micropowder is very difficult. It is not only a process of refinement as a particle, but also changes in chemical properties can be learned along with crystal structure and surface physics. Therefore, the production process of diamond micropowder is a multi-disciplinary engineering and technical issue involving machinery, powder engineering, mechanics, physical chemistry, modern instruments and detection technology.
