Industrial Synthetic Saw Grit Diamond Powder For Cutitng & Drilling

Insulation LED LCD Diamond Grinding Powder 60/80 Mesh

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 90 Series Mesh Size Available:

HID 80 Series Mesh Size Available:

Characteristics: It is widely used in cutting, grinding and drilling because of high hardness and good wear-resistance. It can be used as heating panel of semi-conductor device because of low thermal conductivity and excellent insulation. It is widely used in electronics industry because of good visible transparent and corrosion resistance.
Applications: Geological and petroleum drill bit diamond, diamond used in dies, abrasive, dresser, glass, hardness tester and handicraft.

HID Saw Grit Diamond include HID90 & HID80 series, both of which has complete specifications, various sizes and grades. They are able to produce variety tools for stone, construction and mining industries. The diamond grit particle character (size, strength, crystallinity) plays a major role in understanding the behaviour of grit application. All have stable quality and are able to meet different requirements from customers.

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.
