Industrial Synthetic Monocrystalline Diamond Mesh Powder Grade 2240

ODM 35/40 Mesh Monocrystalline Diamond Powder 0.425mm-3.0mm

Description:

Diamond is a simple crystal composed of carbon element formed under high pressure and high temperature conditions in the deep parts of the earth. Diamond is a colorless octahedral crystal whose composition is pure carbon, which is linked by carbon atoms with four-valent bonds. It is the hardest substance known to exist naturally. Since the CC bond in diamond is very strong, all valence electrons participate in the formation of covalent bonds, and there are no free electrons, so the hardness of diamond is very large, the melting point is 6900 degrees Fahrenheit, and the ignition point of diamond in pure oxygen is 720~800℃. It is 850~1000℃ in the air, and it is not conductive.

HID 22 series refers the grits from size 40/50 to size 70/80 which are mainly used to produce saw blades. The quality under this series is good enough to substitute the imported materials that are produced by belt press

HID 21 series refers to the grits with size bigger than 35/40 (0.425mm-3.0mm). Compared with HID 21 series,these grits are bigger and with higher quality. All the quality data of this series, such as Ti, shape, color and transparency, can meet the international standards. lt fills up the technology blank on large diamond grits of China and marks that our diamond manufacturing technology reached the advanced level in the world.

Structural Properties
The diamond structure is divided into equiaxed tetrahedral cube and hexagonal crystal system.
In diamond crystals, carbon atoms are connected to each other in a tetrahedral bond to form an infinite three-dimensional framework, which is a typical atomic crystal. Each carbon atom forms a covalent bond with the other 4 carbon atoms via the SP3 hybrid orbital to form a regular tetrahedron. Because the C-C bond in diamond is very strong, all valence electrons participate in the formation of covalent bonds, and there are no free electrons. Therefore, diamond is not only hard, but also has a very high melting point, and it is also non-conductive. In industry, diamonds are mainly used to make probes and grinding tools for drilling, and diamonds with complete shapes are also used to make high-end ornaments such as jewelry, and their prices are very expensive.
