What is Diamond Powder
Jun 22 , 2021

Diamond powder is mainly divided into single crystal diamond powder and polycrystalline diamond powder. Single crystal diamond powder is produced from synthetic diamond single crystal abrasive grains, which are crushed and shaped, and produced by a special process. Polycrystalline diamond powder is made from graphite using a unique directional blasting method. The shock wave of the directional blasting of high-speed explosives accelerates the flight of metal flying pieces and impacts the graphite pieces, which causes the graphite to be converted into polycrystalline diamond. Its structure is very similar to natural carbonado diamond. Its particles are composed of tiny diamond grains combined through unsaturated bonds and have good toughness.


Diamond powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, etc. It is an ideal raw material for grinding and polishing hard alloys, ceramics, gems, optical glass and other high-hardness materials. Diamond powder products are tools and components made by processing diamond powder. TransGrindtools is dedicated to providing suitable diamond tooling at every stage of the concrete grinding or polishing process.


Diamond powder belongs to micron, sub-micron and nano-powder in terms of its particle size. Compared with coarse-grained powder, its specific surface area and specific surface functional groups are significantly increased, so in the production process, the force between the particles is greatly increased. In addition, with the refinement of the particle size, the defects of the particles themselves are reduced, and the strength is bound to increase. It can be seen that the production process of diamond micropowder is quite difficult. It is not only a process of particle refinement, but also changes in crystal structure and surface physical and chemical properties. Therefore, the production process of diamond micropowder is a multi-disciplinary engineering technology issue involving machinery, powder engineering, mechanics, physical chemistry, modern instrumentation and testing technology.
