High Purity Micron Diamond Powder Specially Used For Making PCD/PDC
0.05um-60um PDC PCD Diamond Powder for polishing cemented carbide
Description:
Harmony Industry Diamond is a well-known super-hard material manufacturer in China, which has over 10 years production history and its own technology center that ensure the quality and performance of our products. Diamond powder, micron powder, monocrystal diamond are our hots products, which has large market occupancy at home and abroad.
Diamond powder is the hardest ultra-fine abrasive, which has been widely used in machinery, aerospace, optical instruments, glass, ceramics, electronics, petroleum, geology, military industry sectors, and it is an Ideal material for grinding and polishing cemented carbide ceramics, gems, optical glass, etc. Generally, 0-0.5 micron diamond powder to 6-12 micron diamond powder is used for polishing. 10-15 micron to 22-36 micron is used for grinding. The coarser 12-22 micron is used for fine grinding.
The high-purity treatment of HID A+ and HID A series products using a proprietary post-treatment process ensures that the content of metal and non-metal impurity elements on the surface of the product is extremely low, and the reasonable particle gradation increases the particle tap density, which is more important when the composite sheet is synthesized. Easy to combine and grow stably. With super clean particles surface, total content of all kinds of metal impurities controlled at the ppm level.

Application for Grade HID PCD/PDC Micron Diamond:
- 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!
