SYNTHETIC DIAMOND MICRON AND SUBMICRON POWDERS

 

 

 

The stable relations with synthetic diamond producers and  our own enrichment facilities allow our company to have a wide range of fine-purity diamond raw materials for producing micron and submicron powders.

Our production of micron powders includes the sector of diamond grain grinding with a subsequent purification, the sector of water treatment and the sector of classification.

Micron powders within the grain-size range of 60 to 7 microns are produced by a liquid sedimentation process, and micron powders and submicron powders within the grain-size range of 7 to 0 microns are produced by a rotor centrifugation process.

 

 

Our company makes the following range of synthetic diamond micron and submicron powders:
