Monocrystalline silicon and polysilicon Silicon belongs to hard and brittle material, mohs hardness is 6.5, can make polycrystalline silicon, monocrystalline silicon according to the use. Monocrystalline silicon (MONocrystalline silicon) is a relatively active nonmetallic element. With a basically complete lattice structure, monocrystalline silicon (MONocrystalline silicon) is a good semiconductor material with a purity of 99.9999%. It is mainly used for manufacturing semiconductor devices and solar cells. Monocrystalline silicon  is usually manufactured by first producing polycrystalline silicon or amorphous silicon and then growing rod-like monocrystalline silicon from the melt by the direct pull or suspension zone fusion method. Polycrystalline silicon  is a form of elemental silicon. When molten elemental silicon solidifies under the condition of supercooling, the silicon atoms are arranged into many crystal nuclei in the form of diamond lattice. For example, these crystal...

Different grinding wheels should be used for different workpiece materials and different processing requirements. Even if grinding the same workpiece material, the grinding ratio of different brands of grinding wheels may differ by 2~5 times, so the appropriate grinding wheel should be selected. Performance interpretation Diamond grinding wheel is the best grinding tool for hard alloy, optical glass, ceramics, gemstones and non-metallic materials with high hardness and high brittleness such as stone. But because diamond is easily carbonized at 700℃~800℃, it is not suitable for grinding steel. CBN slightly inferior to the hardness of diamond, but its thermal stability (which can withstand temperatures up to 1300 ℃ ~ 1400 ℃), it is not like a diamond in the high temperature decomposition, namely, oxidation and graphitization, and the elements of iron group chemical inertness, high thermal conductivity (46 times that of corundum), made of the grinding wheel long life (up to several dozen...

1. Diamond grinding wheel  series: Artificial diamond, also known as "industrial diamond", is the hardest substance known to man in nature today, as is natural diamond. Due to its high hardness, compressive strength and wear resistance, acid and alkaline resistance, as well as good thermal conductivity and semiconductor properties, it is made into a variety of tools products can be widely used in metallurgy, machinery, geology, petroleum, electronics, optics, construction, stone and other fields. Artificial diamond grinding wheel is a kind of artificial diamond product made from artificial diamond and other metal powder through high temperature and pressure, which can be widely used in the grinding of hard alloy, non-ferrous metal and non-metal. 2.Particle size to choose The size of synthetic diamond is indicated by its size number. The size of the workpiece directly affects the surface roughness, grinding efficiency and tool loss. In principle, the choice of particle size is...

Features of  pcd tools Polycrystalline diamond (PCD) is a polycrystalline sintered microcrystalline diamond powder with a small amount of metal powder (such as Co) and sintered at high temperature (1400 ° C) and high pressure (6000M Pa). Compared with other tool materials, PCD has extremely high hardness and wear resistance, high thermal conductivity, low thermal expansion coefficient, small friction coefficient, fast cutting heat dissipation, low cutting temperature, small thermal deformation, and can reduce the surface roughness of processing. Features. However, because PCD has a strong affinity with iron group elements, it is not suitable for processing ferrous metals and their alloys. The commercially available PCD composite sheet is prepared by sintering a PCD layer with a thickness of 0.5 to 0.7 mm on a cemented carbide substrate, so it has both the high hardness of PCD, high wear resistance and good cemented carbide Strength and toughness. PCD tools show excellent cut...
