1.Breif Introduction
Graphite /ˈɡræfaɪt/, archaically referred to as Plumbago, is a crystalline form of carbon, a semimetal, a native element mineral, and one of the allotropes of carbon. Graphite is the most stable form of carbon under standard conditions.
Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Graphite may be considered the highest grade of coal, just above anthracite and alternatively called meta-anthracite, although it is not normally used as fuel because it is difficult to ignite.
The natural graphite using the chemical effect can existing compound inside. Under the high temperature let if decompose in short time then graphite’s volume rise to 100~~400 times.
This is called expandable graphite also called “flexible graphite”.
2.Main Features
Character: high expandability, porosity, porosity holes, resistant range under the oxygen—free environment is between -200~~3000℃, and it is chemically stable under high temperature, pressure of radiation.
It is widely used in the sealed material, adsorbent material and in the lithium industry.

4.FAQ
Q: Can you supply samples for us?
A: Yes we can send you sample with few quantity
- Q: It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?
- Suggestion: use a certain amount of concentrated nitric acid infiltrated graphite part, nitrate solution the best there is a certain amount of 1-2 weeks (timing can also be placed with a glass rod, pour stirred) acid, diluted with water to acid and then scrub brush. Because the temperature nitric acid reaction is very slow, but the long-term infiltration, the graphite surface. Especially with the glass contact surfaces may be immersed in a small amount of acid, oxidation, then scrub may have the effect.
- Q: What's the conductivity of graphite powder, silver powder?
- These two values show that the resistivity of silver is small, so the conductivity of silver powder is better
- Q: What is the industry standard of graphite powder coating for casting?
- One is purity, that is, the size of impurities, the smaller the better.
- Q: Can graphite powder be used in lithium batteries?
- Qingdao Huatai graphite more than 20 years experience in the production of graphite powder to tell you that graphite powder can be used in lithium batteries.
- Q: Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?
- Electrostatic earthing or electrostatic eliminator. In fact, there is a certain conductive graphite powder is very fine, but so long as the electrostatic would slightly have great effect, give you two ways, one is the good grounding conductor can be static vibration sieve, go through a grounding wire guide;
- Q: The difference between silicone and silicone?
- Silica gel and grease are helpful to system cooling material, the difference is that the silica gel with good thermal performance and insulation, and will not lose its stickiness pale yellow translucent glue at higher temperatures, mainly used in the surface of the heat radiating sheet sticking device; and the grease is not sticky, is a liquid emulsion or cream like, its role is to fill the gap between the chip and the heat sink, improve the efficiency of heat conduction.
- Q: Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.
- Powder resistivity tester, the sample broken to 0.3 ~ 0.5mm, into the powder resistivity instrument insulation sleeve, the tube diameter of 16.3mm, in the bushing into the sample.
- Q: Main ingredients of graphite powder?
- There are water, asphalt, CO2, H2, CH4, N2 and other gas parts. Therefore, the determination of graphite, in addition to the determination of fixed carbon content, but also the simultaneous determination of volatile and ash content.
- Q: The axis and drum can use graphite powder lubrication
- This doesn't seem good. Graphite powder is a solid lubricant. It is suitable for heavy equipment lubrication. The axis and drum or low viscosity lubricating grease is better, so fast.
- Q: What kinds of graphite powder has it? What's the function?
- Its main use focuses on sealing and lubrication, and stone toner is powder, is the basis of other graphite products
