Monocrystalline Industrial Micron Diamond Green Powder Grade HID G

Harmony RVD Diamond Finishing Powder w0-0.5 to w6-12

Description:

The diamond structure is divided into equiaxed tetrahedral cube and hexagonal crystal system.
In diamond crystals, carbon atoms are connected to each other in a tetrahedral bond to form an infinite three-dimensional framework, which is a typical atomic crystal. Each carbon atom forms a covalent bond with the other 4 carbon atoms via the SP3 hybrid orbital to form a regular tetrahedron. Because the C-C bond in diamond is very strong, all valence electrons participate in the formation of covalent bonds, and there are no free electrons. Therefore, diamond is not only hard, but also has a very high melting point, and it is also non-conductive. In industry, diamonds are mainly used to make probes and grinding tools for drilling, and diamonds with complete shapes are also used to make high-end ornaments such as jewelry, and their prices are very expensive.

Monocrystalline diamond powder is a new type of super-hard abrasive, which is mainly used for manufacturing tools used in the process of processing high-hardness and high-precision articles in industrial production.
Currently, it is generally used for polishing from w0-0.5 to w6-12. W15-10 to w22-36 for grinding; W12-22 coarse for fine grinding.
It has the following important features:
1. Strictly control the size classification
2. Uniform particle shape characteristics
3. Control raw materials

Application for Harmony Micron Diamond Powder:

- Traditional gem polishing: single crystal powder or abrasive paste of about 3um is traditionally used
- Raw material for sintering PCD: Micron-sized powder is expanding with the application of PCD tools.
- Grinding and polishing of sapphire wafers: micron to sub-micron, polycrystalline/single crystal polishing liquid is developing rapidly with LED.
- Grinding and polishing of optical fiber connectors: micron to sub-micron, polishing film.
- Ceramic processing: single crystal or polycrystalline powder can be used. For example, fiber ceramic ferrule: single crystal powder from micron to sub-micron, application products include grinding wheel, grinding fluid, polishing film. The application prospects in this area are good.
- Magnetic head: such as grinding and polishing of GMR magnetic head, submicron ~ nanometer, polishing liquid/polishing film.
- Grinding and polishing of super-hard metal rollers or devices: micron to sub-micron, polishing film/abrasive paste/grinding wheel develops steadily.
- Polishing of metal molds: micron to sub-micron, diamond polishing liquid/grinding paste is developing steadily.
- Raw materials for various grinding tools: single crystals of various grain sizes, there is still broad room for development!
