Grade HID 960 Mesh Size 30/35 Saw Grit Synthetic Diamond Powder

D601 30/35 Saw Grit Diamond Powder for electronic industries

Description:

As the hardest material known, synthetic diamond monocrystal is widely used for metallurgy, oil drilling, construction engineering, mechanical processing, instruments, electronic industries, aviations and space field etc.

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.

Stability of diamond

Diamond has stable chemical properties, acid and alkali resistance. It does not interact with concentrated HF, HCl, or HNO3 at high temperatures. It only works in the melt of Na2CO3, NaNO3, KNO3, or when it is boiled with the mixture of K2Cr2O7 and H2SO4. Slightly oxidized; corrodes in high temperature gas of O, CO, CO2, H, Cl, H2O, CH4.
Diamond also has non-magnetic properties, poor electrical conductivity, lipophilic and hydrophobic properties, and triboelectric properties. Only type IIb diamond has good semiconductor properties. According to the difference in nitrogen impurity content and thermal, electrical and optical properties of diamond, diamond can be divided into two types, type I and type II, and further subdivided into four subtypes: Ia, Ib, IIa, and IIb. Type I diamonds, especially Ia subtypes, are common ordinary diamonds, accounting for about 98% of the total natural diamonds. Type I diamonds all contain a certain amount of nitrogen and have good thermal conductivity, poor electrical conductivity and good crystal shape. Type Ⅱ diamond is extremely rare, contains little or almost no nitrogen, has good thermal conductivity and characteristics of curved crystals. Subtype IIb diamond has semi-conductivity. Because of the excellent properties of type II diamond, it is mostly used in space technology and cutting-edge industries.
