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: Is graphite powder conductive?
- The bottom current may be the internal resistance of the battery is too large, in addition to graphite reasons, the contact state of battery cathode and graphite copper check, graphite powder, no contact measurement, the conductivity of no experience, resistance measurement of graphite column can be compared (with the current large and small current comparison test),
- Q: Whether the lubricating oil toner is coupled with the conductor?
- But with graphite, it will make the metal contact sheet and the whole resistance to form the passage, rheostat can not change the role of resistance. I actually lubricate, that is, with cotton swabs dipped in lubricating oil, and then put a touch on it.
- Q: How to identify iron powder and graphite powder in a simple way?
- Can also take the first touch, using magnets to attract or drop method with acid identification of three substances. [a] analytical method (first touch after magnet): touch the two kinds of powder by hand, are oily powder graphite powder, and then take the other two kinds of powder with a magnet, the magnet can be as for iron, can not be sucked up into powder;
- Q: Can graphite be made directly from graphite powder? How about the effect?
- Let the graphite powder stick into shape. The commonly used asphalt in the industry is used as binder, and graphite powder and asphalt are mixed and pressed to form. It is also necessary to heat, roast and graphitized the asphalt in the graphite blocks to obtain certain heat conducting, conductive or other uses of Shi Mobang.
- Q: What graphite powder made of graphite products, high hardness?! Wear-resisting！ Good moisture! It can be made into graphite products at 100-200 degrees high temperature
- Graphite powder is divided into natural graphite powder and artificial graphite powder, graphite powder made of graphite products, you need to add binders, binders useful for a variety of resins, asphalt and so on.
- Q: Is the graphite powder poisonous?
- There are three kinds of substances that fly out of the black spot from the carbon factory:1. Bituminous dust.2. A relatively fine particle of calcined coke (petroleum coke after calcination).3. A fine particle of calcined and graphitized Shi Mofen (calcined coke and bituminous mixture).Both poisonous.
- Q: What is the use of flake graphite in making flake graphite powder?
- Better for corrosion protection coatings, fire retardant coatings and conductive coatings.
- Q: What mask should be used to prevent stone powder?
- As enterprise owners, should actively take labor protection measures, do not mean this little money, because if workers suffer from silicosis, treatment and late payment of responsibility is the business owner himself. This runs the risk of.
- Q: How much is the price of graphite powder for a ton?
- Battery with graphite powder to Qingdao Chenyang graphite Co., the quality is reliable, trustworthy
- Q: Crystal graphite of graphite powder
- Pure graphite flake graphite and high directional pyrolytic graphite, which have less defects and larger sizes, can generally be considered as perfect graphite single crystals. Considerable research has been done on the thermal conductivity of such graphite. Under compressive stress, the pyrolytic graphite above 3000K processing, the bulk density is 2.25g/cm, 2.266g/cm is close to the theoretical density of the single crystal, the half width of the diffraction peak (002) show only 0.4 degree angle (mosaic angle), is also very close to the theoretical value of zero. The thermal conductivity of this graphite is shown in table 1. These values are generally considered to represent the corresponding values for single crystal graphite. The thermal conductivity along two principal directions is denoted as lambda a along the layer, and is marked by lambda C along the vertical plane.
