| Application areas | NAT diamond is suitable for the production of electroplated diamond tools such as grinding wheels, drills and saws. In loose particle form, NAT diamond is used for polishing of diamond wire dies made of natural diamond and PCD. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Gradings | Precision size range: A narrow particle size distribution maximizes the amount of particles of the same size while fine and coarse particles are minimized. Combined with a clearly defined upper size limit, this feature allows for both high process reproducibility and superior results in surface quality. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Morphology | Blocky particle shape: NAT diamond has the same monocrystalline structure as synthetic diamond, but without the traces of metal catalysts which are inherent to synthetic diamond. Natural diamond features distinct cleavage planes. This results in blocky and irregular shaped, free-cutting particles. For bonded diamond tools, the fracturing mechanism of the diamond provides a self-sharpening of the tool which increases its service life. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Synthesis | NAT diamond is processed from mined industrial quality natural diamond. Diamond is formed in depths of several hundreds of kilometres underground in conditions of high pressure and high temperature. Volcanic activity eventually forces the diamond to the earth’s surface. NAT diamond particles are of a monocrystalline structure featuring cleavage planes oriented parallel to the optical axis. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
