| Nano diamond powders, our nano grade diamond polishing powder / lapping powder / finishing powder is produced from the dissociative carbon in super high pressure and temperature during the detonation by the oxygen-negative explosive. The nano diamonds, with 5 - 20 nanometer basic sizes, have sphere shape and functional group of oxygen and nitrogen on the surface. It possesses characteristics of both diamond and nano functional material. |
| nanometer diamond is achieved from the dissociative carbon in super high pressure and temperature during the detonation by the Oxygen-deficient explosive. The nanometer diamonds, with 5 - 20 nanometer basic sizes, have sphere shape and functional group of oxygen and nitrogen on the surface. Specific surface area of nanometer diamond improves an order of magnitude more than common diamond. It possesses characteristics of both diamond and nanometer functional materials. Depending on requirements of different applications, nanometer diamond primary products should pass procedure of purification, surface modification and precise grading treatment, which are our exclusive technology. Different post-processing can separately achieve black powder products (containing graphite carbon layer on the surface) and pure grey nanometer diamond powder products; therefore, we can provide all series of nanometer diamond products with full specifications and types. |
| Nano diamond powders characteristics for Super finish polishing :
1. Stable high dispersibility 2. Various dispersible products 3. Characteristic anti-causticity. 4. High specific surface area,porous structure. 5. Superhigh purity, main element impurity below 30 ppm 6. Super polishing effect with minus 0.8 nm surface roughness 7. Characteristic surface modification treatment makes stable dispersion in both water & oil medium. 8. High electrical & thermal conductivity. Outstanding wearability, anti-causticity and thermal conductivity 9. Mature stable grading technics make our products suitable for all fields that ask for strict requirements of PSD. 10. Superhigh purity, main metal impurity below ppm, purification and surface modification treatment for different needs make surface functional group controllable. 11. Basic particles are sphere shape diamond crystal grains, which form stable specifications through secondary aggregation due to the features of nanoscale products and also possess the resistance & hardness of diamond. |
