Monocrystalline Mesh Diamond Powder Grade 2215 For Low Grinding

HTHP Monocrystalline Diamond Grinding Powder Irregular Shape

 

Description:

Diamond is a mineral composed of carbon. It is an allotrope of graphite with a chemical formula of C. It is also the original body of common diamonds. Diamond is the hardest substance naturally occurring in nature. Graphite can form synthetic diamonds under high temperature and high pressure. Diamond has a wide range of uses, such as handicrafts, cutting tools in industry, and it is also a precious gemstone.
Diamonds come in various colors, from colorless to black, with colorless ones being particularly preferred. They can be transparent, translucent or opaque. Many diamonds are yellowish, which is mainly due to impurities in the diamonds. The refractive index of diamond is very high, and the dispersion performance is also very strong, which is why the diamond reflects colorful flashes. Diamond will emit blue-green fluorescence under X-ray irradiation. The primary diamond ore is only produced in the Kimberlite tube or a few lamprophyre rocks. Kimberlite is their parent rock, and diamonds in other places are transported by rivers and glaciers. Diamond is generally granular. If the diamond is heated to 1000°C, it will slowly turn into graphite.

 

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.

Introduction of synthetic diamond

There are two main methods of synthetic diamond, high temperature and high pressure method and chemical vapor deposition method.
The high temperature and high pressure method technology has been very mature and has formed an industry. The domestic output is extremely high, the highest in the world. The chemical vapor deposition method still mainly exists in the laboratory.

 

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.
