Product Description:

High carbon graphite powder

 

High carbon graphite powder is a manufactured product made by high-temperature treatment of amorphous carbon materials. In our manufacturing plants, the primary feedstock used for making artificial graphite powder is calcined petroleum coke and coal tar pitch, both of which are composed of highly graphitizable forms of carbon.

 

The manufacturing process consists of various mixing, molding, and baking operations followed by heat-treating to temperatures between 2500 C and 3000 C. The ultra-high heat treatment temperature is required to drive the solid/solid, amorphous carbon-to-graphite phase transformation. The morphology of most artificial graphitepowder varies from flakey in fine powders to irregular grains and needles in coarser products.Artificial graphite powder is processed at ultra-high temperatures, and impurities contained in the precursor carbons are significantly reduced in concentration during processing. This occurs as a result of the high temperature vaporization of volatile impurities, which at the process temperatures utilized includes most metal oxides, sulfur, nitrogen, hydrogen, and all organic components that were part of the original petroleum or coal tar pitch.

 

As a result of this thermal treatment, virtually all artificial graphite products are high purity. Artificial graphite is available in particle sizes from 2-micrometer powders to 2 cm pieces. Purities are typically 99+% carbons.Artificial graphite is used in many applications including but not limited to friction, foundry, electrical carbons, fuel cell bi-polar plates, coatings, electrolytic processes, corrosion products, conductive fillers, rubber and plastic compounds, and drilling applications.

 

high carbon high pure  artificial  graphite powder

 

Use:widely applied to high quality fire resistance material and coating of metallurgy industry,hot working material stabilizer of military industry,lead of light industry,carbon brush of electrical industry,electrode of battery industry,and catalyzer and additive of fertilizer industry.After further process,scale graphite can be made into the following high-tech products such as graphite colloidal graphite,graphite compacting material and composite material,graphite products,and graphite anti-friction additive,which are becoming important nonmetal mineral materials in every industry.

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:What is the simple test method for graphite powder used in casting?
Now the domestic inspection method of carburizing agent is the national standard of coal inspection method, the specific test of carbon content, volatile content, moisture, ash, sulfur and so on. The easiest way is to draw on the paper, drawing trace smooth, obvious is not obvious graphite products, may be coal or petroleum coke graphite the powder
Q:How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
Method 1: (1) attract by magnet respectivelyIron powder can not be attracted by the permanent magnet, the magnet, the magnet can be graphite powder(2) take the powder which can not be attracted by magnet, and add dilute hydrochloric acid respectivelyThe reaction is more intense, there are more bubbles are aluminum powder; no obvious phenomenon is graphite powder (not reaction)
Q:Does graphite allow lubrication of rusted doors?
Tolerable。 However, there is a premise: rust must be removed with rust.Lock force rust is generally not easy to lock inside the material easily rust off, then need to use oil to rust, rust removing, the graphite powder filling hole, and then the key to rotate back and forth, you can make the door lubrication.
Q:What's the conductivity of graphite powder, silver powder?
The resistivity of graphite is approximately (8~13) * 10-6.M at room temperature
Q:Method for identifying iron powder, aluminium powder and graphite powder
1. aluminum powder is silver, black substance attract rest with a magnet that attracted iron, not be attracted to the graphite2. Add equal mass, such as concentration of dilute hydrochloric acid, the gas is fast aluminum powder, slow iron, and do not produce gas is graphite.
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: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:Classification of graphite powders
High purity sub micron graphite particles have a very wide range of applications: electronic information industry, CRT display manufacturing black conductive coatings, by the use of liquid crystal display device, a sensor and a color decomposition device on the photosensitive black film, flat panel display color liquid crystal color plasma for improving emission effect and part of state color contrast, ultrafine tungsten, molybdenum wire drawing and other senior paint, lubricating oil and grease manufacturing, high performance battery manufacturing and foam iron nickel film is widely used in many industries such as high purity sub micron graphite particles.High pure graphite superfine powder colloidal graphite powder, mainly used in powder metallurgy, pen special, special lubricating oil, lubricating grease, special special batteries special conductive coating, special, special coating, lubrication of defense, scientific research institutions of scientific research, civilian nuclear power, aerospace and special special strategic weapons power interference smoke bomb, shielding, colloidal graphite powder production in China is the development of industry of our country graphite industry pacesetter, part of the technology has reached the international advanced level.
Q:Are sand and particle powders used for casting quartz sand? Detailed and accurate.
Casting molding mainly used for special silica sand, zircon sand, magnesia and chromite, pearl sand, graphite sand. Casting powder mainly used in coatings, such as: quartz powder, bauxite powder, zircon powder, graphite powder, etc.
