Polycrystalline diamond micropowder: Polycrystalline micron diamond powder is produced by detonation synthesis of high-energy explosives under negative oxygen conditions. The ultra-high pressure and high temperature conditions necessary to synthesize diamonds at the instant of detonation, and the free carbon atoms generated by the explosives form micron-level Diamond particles. Micro-diamonds are different from the ordinary hydrostatic synthetic diamonds. The shape of the micro-diamonds is an irregular quasi-circular block, with sharp peaks and edges, and better self-sharpening.
Polycrystalline diamond is used as ultra-precision polishing and grinding materials for ultra-precision polishing of magnetic heads, hard disks, gems, LEDs, hard glass, ceramics, and hard alloys; (computer disks, magnetic heads, optical communication devices, optical crystals, semiconductor-based Tablets, etc.); can also be used as an additive for lubricating oil, solid lubricants, lubricating coolants or engine oils, which can greatly improve the operating performance of industrial machinery and vehicles, reduce failures and extend service life.
Single crystal diamond micropowder: The crystal shape is a regular, complete hexahedral octahedron with high strength, toughness and good thermal stability, and strong impact resistance. It is suitable for the manufacture of electroplated products, grinding wheels and grinding wheels. It is used for polishing, engraving, automotive glass, high-grade furniture, ceramics, hard alloys and magnetic materials for high-grade stone.
Nano-diamond micropowder: Nanocrystalline diamond is synthesized under the action of transient strong shock wave formed by explosion. It is a micron and submicron polycrystal composed of nanocrystals. Because of its isotropy, no cleavage surface, high impact resistance and high flexural strength, it has the hardness of superhard materials and nanometers. The material is exceptionally high strength and high toughness. Its dual advantages constitute its unique physical properties, and it has important applications in high-tech industries and traditional pillar industries. Mainly used in chip optical crystal \ ultra-fine processing, large-scale wafer super-fine polishing, surface modification and other fields, spherical polycrystalline diamond micro-powder appearance gray-black, slightly metallic luster.
Nano Diamond not only has the inherent characteristics of diamond, but also has small size effect, large specific surface area effect, quantum size effect, etc., thus exhibiting the characteristics of nano materials. The diamond synthesized in the detonation wave has a cubic structure, a lattice constant of (0.3562 + 0.0003) nm, a crystal density of 3.1 g/cm3, and a specific surface area of 300 m2/g to 390 m2/g. After different chemical treatments, a variety of different functional groups can be formed on the diamond surface, and this diamond crystal has a high adsorption capacity.
Other uses of nano-scale diamonds: Preparation of advanced abrasive pastes and polishing fluids: for ultra-fine processing of quartz, optical glass, semiconductors, alloys and metal surfaces, which can effectively improve the processing accuracy.
