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 the graphite electrode broken like graphite, fossil oil, coke and graphite powder?
- The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
- Q: The graphite powder can replace thermal grease?
- Graphite is non-toxic, but graphite powder is harmful to human body; and graphite is used mostly in conductive products (common battery).
- 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: What is the use of flake graphite in making flake graphite powder?
- Flake graphite is widely used in advanced refractory materials and coatings of metallurgical industry. Such as bricks, crucible etc.. Military industrial explosive materials stabilizer, smelting industrial desulfurization growth agent, light industry, electrical industry pencil brush, industrial battery electrode and catalyst in chemical fertilizer industry, etc.. Flake graphite is further processed and can be used to produce graphite milk. It is used as lubricant, release agent, drawing agent and conductive paint. Expandable graphite can also be used for flexible graphite products, such as flexible graphite seals and flexible graphite composite products.
- Q: How to measure the iron content in graphite powder?
- Take a certain amount of samples, adding dilute hydrochloric acid, excessive filtering and drying. The quality of the filter residue. By weighing the quality of the sample quality is the quality of minus slag containing iron. With this value divided by the sample quality, the mass fraction of iron.
- Q: Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you
- A magnet attracts iron powder... Take the same volume of two substances, respectively, in the hands of weighing, the heavier iron powder
- Q: What solvent can be used to dissolve Teflon?
- PTFE is not dissolved after Teflon, it is impossible to mix with graphite powder this thing.
- Q: What companies use graphite powder, graphite particles, graphite ball, silicon carbide alloy ball?
- Refractory industry, because of the high temperature resistance of graphite and silicon, it will be applied in refractory industry.
- 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.
- Q: Why can graphite powder conduct electricity?
- Graphite is a crystalline mineral of carbonaceous elements. Its crystalline framework is hexagonal layered structure. The distance between each network layer is 3.40, and the distance between the carbon atoms in the same network layer is 1.42A. Of the six Fang system with a complete lamellar cleavage. The cleavage surface is mainly based on molecular bonds, and has weaker molecular attraction, so its natural floatability is very good.
