Introduction High purity graphite powder Graphite is a black-gray powder that is very soft. It can cause a greasy residue on the paper. The hardness is approximately 1 2. In the vertical direction, with an increase in impurities, it can go up to 3 5. The specific gravity of the mineral is 1.92.3. It can melt above 3000 when it is oxygen isolated, making it one of the most high-temperature resistant minerals.

High Purity Graphite Pulp
At room temperature the chemical properties graphite are stable and insoluble in water, dilute pH, dilutealkali, organic solvents, and alcohol. They can also react with oxygen at high temperatures to make carbon dioxide or carbon monoxide. In halogens, only fluorine is allowed to react with elemental carbon. Graphite powder can easily be oxidized by acids under heating. It reacts with many metals, producing metal carbides. These can also be melted at high temperature.
High purity graphite dust High-temperature resistance, electric conductivity and lubricity. Also, chemical stability, plasticity and thermal shock resistance.
Nanocrystalline graphite of high purity Has the outstanding quality, high fixed Carbon composition, lower harmful residue, sulfur, and stable physical properties. It is a top-selling high purity graphite in the world.

High Purity Powder Graphite
You can use graphite powder as a refractory material, conductive material, casting, sand and molding, and high-temperature metalurgical materials. It can also be used for boiler scaling prevention, pigmentation, and polishing agent.
1, as refractory substances: graphite or its products with higher temperature resistance, high strengths properties, in metallurgical industries is primarily used to produce graphite Crucible, in steelmaking graphite can be used as a protective agents of ingots, metallurgy oven lining.
2, as conductive materials: used in the electric industry to make electrodes and graphite gaskets. Telephone parts, TV picture tube coatings, etc.
3: Graphite is often used as a grease in the machinery sector. Lubricating oils can often not be used at high speed, high temperature, and high-pressure conditions. However, graphite materials are capable of sliding at 200 to 2000 degrees Fahrenheit, with no lubricating fluid work. In many equipment used for conveying corrosive materials, graphite bearings are common. They don’t require any lubricating oil for running. Graphite is a good lubricant when processing metals (wire drawing, tubing).
4, casting, aluminum casting. Molding and high-temperature metallic materials: The graphite’s small thermal expansion coefficient and ability to change the thermal shock make it suitable for glass mold. Once graphite black metal casting dimensions conform to your requirements, the surface will be bright and clean with high yield. This allows you to save large amounts of metal.
5 graphite can also prevent boiler scale. The relevant unit testing shows that the amount added to water (45 grams per ton) can prevent boiler surfaces from scaling. Graphite can also be coated on metal chimneys or roofs.
6. Graphite can be used to polish and pigment.
