Natural abrasive is a hard material found in the earth and is used to shape other materials by grinding or abrading. Natural Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications...

Synthetic diamond is produced synthetically in a high temperature, high pressure process anvil press. Diamond is superabrasive grain with the highest known hardness and a cubic crystal structure.

Cubic boron nitride, CBN for short, is a kind of artificial superhard materials with its hardness only second to diamond, and its natural form hasn’t been discovered at present.

Polycrystalline diamond, PCD or TSP for short. At present, it can be roughly divided into three types according to the sintering mechanism.

Polycrystalline CBN, or polycrystalline cubic boron nitride (PCBN), are produced by sintering micron CBN (cubic boron nitride) powders with various binding materials.

CVD is a short form for Chemical Vapor Deposition, which is a chemical process used to produce high-purity, high-performance solid materials.

Nano diamond’s manufacturing and application have always been a hot topic of scientists from all over the world in recent years.
