Polycrystalline Structure Diamond Powder
Sub-Micron Size Premium Grade Detonated Diamond Powder DP-1
This product is the result of the discovery of a new technology. These synthetic polycrystalline diamonds are produced by using short, powerful explosions, that transform graphite into diamond. The process yields polycrystalline diamond crystals each consisting of thousands of microcrystallites bonded together.
The polycrystalline diamonds are the only type of diamonds that have self sharpening properties, The polycrystalline structure will open new sharp edges by releasing the outer layer of dull microcrystallites.The polycrystalline can lap and polish any materials faster than any other abrasive while producing the smoothest, most scratch free surface possible.
Most efficient areas of application
- Water and oil based polishing products to be used for metals and their alloys, ferrites, silicons, sapphires, glass, etc., allowing the level of polishing up to 1.2 x 10-5 in. (0.0003 mm) with coefficient of diffusive reflection 0.4-0.7%.
- As an additive for soft magnetic amorphous alloys used in magnetic recording systems which can increase the coating wear resistance three to five times.
