Monocrystalline micron diamond powder, selects high quality synthetic diamond as the raw material, adpots different production processes and product standards according to the requirements of different industries and application fields.
Polycrystalline diamond is produced by detonating with high energy explosive, the high explosive heat and high detonating pressure change the graphite into poly diamond which structure is similar to natural carbonado diamond. Due to the extremely short synthesis time, there are some lattice defects inside the crystal, almost all the diamond particle is composed by integrating the basic grains less than 100nm together through sharing the crystal surface. In the processing of some special materials, polycrystalline diamond will not produce deep scratches on the workpiece, at the same time , after a certain pressure, the microcrystal grain on the diamond surface will peel off and form new cutting edge continuously. These characteristics provide solutions for the rapid grinding and polishing of some high hardness special materials. Experiments show that the removal rate of poly diamond is 2- 4 times higher than common diamond and without scratches.
Nanometer diamond powder is formed with tiny crystals below 20 nanometer, the special detonative condition produces sphere shaped diamond with rich functional group on the surface,its specific surface area is increased by one order of magnitude contrasted with the monocrystalline diamond. This product not only has the excellent hardness and grinding characteristics of diamond, but also has the new characteristics of nanofunctional materials.
The particle shape is porous structure, and the surface has a large number of sharp cutting edges. After grinding and polishing, the surface Ra value is significantly reduced, which is widely used in precision grinding and polishing of hard and brittle materials, such as sapphire, silicon carbide crystal and ceramic materials.
Aggregated diamond is a spherical polycrystalline-like diamond powder, which have unique polycrystalline-like structure and widely used in grinding and polishing of hard and brittle materials such as sapphire wafers, silicon carbide wafers and functional ceramics.
