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.
Features

- Low ash and sulfur contain
- Reduce needs for expensive melt additives.
- Increased dissolution rate over anthracite blends
- Reduces slagging time, labor and disposal costs.
- Extends the life of the furnace lining, reduce maintenance cost and increase production yield.
Application
- Used in metallurgy industries as carbon additive
- Lubricant for industries use
- Production of fuel cell, bi-polar plates, coating.
- Used in electrolytic processes, corrosion products, conductive filler, rubber and plastic compound.
- Q: Can I use super fine stone powder in grease or lubricating oil?
- Yes, it can play a role in increasing extreme pressure. But it has little effect on low temperature and high temperature resistance. It can not play the role of total synthesis of molybdenum disulfide high temperature grease.
- Q: Does the pencil core go into the baby's face to keep the skin tight?
- One possible problem is that even if there is no breakage, but there may be residual graphite powder cartridge inside, more so, good after the wound will leave behind a black spot (a little like the indistinct).
- 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: How does graphite powder look good or bad?
- Graphite powder is a kind of negative electrode material for batteries.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, wet material will be selected to bagging dry dry machine, shower shower has become dry, dry material is graphite products. Will pour into the dry drying workshop, drying after bagging, namely ordinary graphite powder, the carbon content of the finished product is an average of 90%.The utility model relates to a pencil core, a graphite electrode for a battery, and a lubricant for a cable carA dark gray, metallic opaque opaque flaky solid. Graphite is very soft, creamy feel. It has excellent electrical conductivity
- Q: For thermal grease skills, the more detailed the better
- But this is not possible, the metal lid heat sink and CPU looks smooth, but with a magnifying glass, you can see many holes in metal surface concave stripes and irregular tunnel, lead contact surface with many gaps, these gaps are impeding heat dissipation, thermal grease is liquid, can fill the gaps. Improved radiating surface contact, the heat dissipating effect than when there is no good thermal grease. But if the thermal grease is too thick, it will become a film on the contact surface of the middle, but hindered the direct contact of metal, worse than not coated with thermal grease.
- Q: Graphite powder what is the difference?
- Graphite is a isomer of carbon, chemical symbol C, non-metallic, non-toxic, relatively smooth, can be rubbed on the key, harmless to the baby.
- Q: Is graphite powder dangerous?
- Has excellent conductive properties. The color steel gray or gray, with metallic luster, with lubrication, easy dyes, chemical stability, heat conductivity, good heat resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, due to its small crystal plasticity, good adhesion, so it does not belong to dangerous goods!
- Q: The difference between silicone and silicone?
- The characteristics of silicone grease:The application of silicone grease is more widely than silica gel. Many industrial heat places are using thermal grease. Many different types of people and grease, by adding some "impurities" to its thermal conductivity to improve pure thermal grease. These impurities are graphite powder, aluminum powder, copper powder, silver powder and so on. Pure pure silicone is pure white or milky white, the color of the doped graphite grease dark black, doped with aluminum grease some gray shiny, slightly gray is silver, and copper doped grease are yellow or yellow.Now some high-grade thermal grease using silver or aluminum powder as filler, with high thermal conductivity of the metal, but relatively large metal particles, filling effect is poor, the performance increase is not large, but the improper use of conductive grease, easy to cause a short circuit.
- Q: How to deal with graphite powder? Anyone recycle it?
- We have a lot of graphite, and now we have it
- Q: How to measure the iron content in graphite powder?
- Excessive amounts of dilute sulphuric acid can be used to measure the amount of gas produced, and then the amount of iron is calculated according to the amount of gas.
