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: What are the specifications of the graphite powder used for conduction?
- Graphite powder itself is conductive, according to purity, particle size, conductivity is also different
- Q: How do you use graphite powder in copper?
- This question is a bit vague, you can say it, is inlaid with copper and graphite, the graphite powder melt into the copper, if it is the former, is easy to do, if it is the latter, it is necessary to copper melting after adding graphite powder, the latter is relatively difficult.
- Q: How many kinds of lubricating graphite powder can be added to the car engine?
- The scale and rust in the water tank are not very strong. It is a little growth. Graphite powder added, good dispersion, destroy the growth condition of scale and rust, no longer changxin. Then, have grown in water flow, under agitation, a little bit is washed down, and can no longer stick back, then, are in the water.
- Q: Use of carburizing agents
- Recarburizer steelmaking using recarburizer (People's Republic of China ferrous metallurgy industry standards, YB/T 192-2001 steel with increased carbon agent) and cast iron using recarburizer, and add some other materials are useful to the carburant, such as brake pads additive for friction materials. The carburizing agent belongs to the raw material of additional steelmaking and ironmaking. High quality carburizing agent is an indispensable additive for the production of high quality steel.
- 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: Is oxygen allowed in the oxygen pipe?
- To tell the truth, the graphite powder also belongs to small particles, if the medical oxygen pipe can not have graphite, if industrial oxygen, can have the physical and chemical properties of graphite, graphite and other stable, will not react, to a certain extent is a kind of preservatives, prevent oxidation function.
- Q: Is graphite powder dangerous?
- Graphite powder graphite is a kind of battery cathode materials. The process of graphite powder, will after the bursting of the raw ore by car to crush the rock breaking machine, and ball mill by flotation, the flotation of graphite ball mill grinding wet material sending selected, will be selected to dry the wet material bagging machine dry a shower, shower is dry, dry graphite finished product.
- Q: What mask should be used to prevent stone powder?
- As an enterprise employee, we must actively advocate the right of labor protection to the enterprise owner, and the stone powder can be worn with industrial masks
- Q: How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
- Method two: Ignite (ignite in oxygen bottle)Iron sparks, release a lot of heat, and generation of black powderAluminum burns violently, gives off dazzling white light, emits a large amount of heat, and simultaneously produces white solidThe graphite powder is formed to clarify the turbid water of the lime waterMethod three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectively
- Q: Why does an electromagnetic point timer not prick a needle and use toner paper?
- With the needle point than the powder paper friction, many experimental results of!
