Classified according to the acquisition method: natural diamonds and synthetic diamonds.
Classified according to structure: hexagonal – structured diamond and cubic – structured diamond.
Classified according to properties: Type I diamond (Type Ⅰa diamond, Type Ⅰb diamond), Type II diamond (Type Ⅱ a diamond, Type Ⅱ b diamond).
Classified according to industrial uses: for resin – bonded abrasives, for metal – bonded abrasives, for saw – cutting – grade diamonds, for electroplated products (requiring weak or extremely weak magnetism).
Classified according to the morphology of diamond: single – crystal diamond, cubic diamond, cube – octahedron diamond (cubic – dominated), cube – octahedron diamond (both forms develop equally), octahedron – cube diamond (octahedron – dominated), octahedral diamond, rhombic dodecahedron diamond (this form can form a rhombus with a cube and an octahedron), other single crystals (mostly in natural diamonds), twin – crystal diamond, intergrowth diamond, dendritic diamond, acicular or flaky diamond.
Classified according to the overall grade: gem – grade diamond and industrial – grade diamond.
1. Large single-crystal particles:
Generally speaking, it should be single-crystal diamonds with a size of no less than 3 mm. On the one hand, they can be directly cut and ground to make diamond cutting tools. On the other hand, they can replace some natural diamonds for use as gemstones. Therefore, they are often referred to as gem-grade diamonds.
2. Extra-large coarse-grained diamonds:
Generally referring to diamonds with a size of 1 to 3 mm. They can be used to make grinding wheels, and some of them can replace natural diamonds for use in making ornaments.
3. Coarse – grained diamonds:
Generally, it refers to diamonds with a size of 0.5 – 1mm. The products here are quite good for making grinding wheels.
4. Medium-coarse grained diamonds:
Generally referring to diamonds of 30 – 60 mesh. This type of diamond plays an excellent role in drilling, especially in stone processing.
5. Medium-fine diamonds:
Most refer to diamonds of 70 – 120 mesh, which are a good choice for the processing of stone, glass and ceramics.
6. Fine-grained diamonds:
Most refer to diamonds of 120 – 325 mesh, which are good materials for the processing of magnetic materials, cemented carbides and so on.
7. Ultrafine-grained diamonds:
Most refer to those of 325 – 700 mesh. They are the top choice products for achieving mirror-finish polishing and can also be widely used in the electronics-microelectronics industry.
8. Diamond micropowder:
It is divided into two categories, namely coarse micropowder and fine micropowder. It is mainly used for polishing and high-precision polishing, and some are also used for high-precision grinding.
9. Nanodiamonds:
The main production method is the explosion method. Dispersion technology and application technology are its core technologies. They are mostly used in the military industry and high-tech industries.
