What is diamond powder?

2023. 02. 13

Diamond powder, as a kind of super-hard abrasive, has the incomparable grinding ability of other products and is highly valued by industrial developed countries. It usually refers to diamond particles with a particle size between 0.1 and 54 μm, and those smaller than 5 μm are also called fine micropowder. 

According to the crystal structure, they can be divided into monocrystalline diamond powder and polycrystalline diamond powder.

  • Monocrystalline diamond powder is produced by artificial diamond single crystal through crushing, shaping treatment and special technology of superhard materials. Its particles retain the single crystal characteristics of monocrystalline diamond, with a cleavage surface, and it is preferred to be broken along the cleavage surface when it is impacted by external force.

    Polycrystalline diamond powder is produced from graphite using the directional blasting method, and its particles are combined by diamond grains through unsaturated bonds, with internal isotropy and no deconvolution surface, and high toughness.

  • Diamond powder is a strategic emerging material with the highest hardness, the best thermal conductivity, the best biocompatibility and the strongest corrosion resistance among the current industrial materials, and it is widely used in photovoltaic, aerospace, electronics, automotive, military, machine tools, precision manufacturing, stone, building materials, oil and gas drilling, geological exploration, coal and mineral extraction, and other areas of national economy and people's livelihood.
