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: What are the hazards of inhalation of graphite dust?
- It must be harmful to human beings! Look at the dictionary of carbon black dust lung disease Description: black carbon pneumoconiosis: long-term inhalation of carbon black dust caused by pneumoconiosis. Carbon black is mainly the quality of easy flying carbon. Although the production has been closed and automated, the phenomenon of dust flying still exists. Therefore, workers who produce and use carbon black may have black carbon pneumoconiosis, the shortest length of onset is 15 years, the longest can be more than 25 years, the clinical symptoms are mild, and the progress is slow, and generally does not affect the ability to work.
- Q: Whether the ordinary graphite powder is sprinkled on the electronic instrument can lead to the malfunction of the instrument
- Ordinary graphite powder is also conductive, but only strong and weak
- Q: Thermal conductivity and density of graphite powder
- In the formula, P is porosity, and lambda 0 is the thermal conductivity without hole (P=0). This formula is of historic significance. For graphite, the pores are not spherical or more unequal, but of course they do not apply. But it shows that the larger the porosity (the smaller the density), the smaller the thermal conductivity. This qualitative conclusion is correct.
- 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: How does graphite powder look good or bad?
- 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: Why does an electromagnetic point timer not prick a needle and use toner paper?
- It's a combination of graphite powder and current to mark the surface of the tape. You can imagine it as an inkjet printer
- Q: Can graphite powder be used as a carburizing agent?
- Basically can be, but to look at your purity, if many impurities can not be used if the carburant is a general term, is all can increase the carbon content of the material referred to a molten iron, graphite powder is then dust too much, when the operation is not clean, too small it is easy to burn and water oxidation, not good,
- Q: Main ingredients of graphite powder?
- These impurities often appear in quartz, pyrite, carbonate and other minerals.
- Q: Graphite powder made of graphite oxide, how much weight gain?
- 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.
- Q: Why does the temperature rise when the graphite powder is turned on?
- What is the value of resistance, and this value is not an accurate number, because the graphite powder thickness is not the same, used in different materials and environment, graphite powder, resistance value will be different.
