High purity Graphite powder (100-600mesh), melting point is above 3000ºC under the condition of oxygen isolation, is one of the most temperature-resistant minerals. At room/normal temperature, the chemical properties of graphite powder are very stable, insoluble in water, dilute acid, dilute alkali and organic solvents. Graphite powder with high temperature conductivity, can be refractory materials, conductive materials, and wear-resistant lubrication materials.
Graphite powder reacts with oxygen at different temperatures to form carbon dioxide or carbon monoxide. In halogens only fluorine can react directly with elemental carbon, Under heating, graphite powder is easy to be oxidized by acid. Graphite powder can also react with many metals to form metal carbide at high temperature, which can applied for metallurgy.
Perfect crystallization, thin flake, good flexibility, excellent chemical and physical properties, superior conductivity, selflubricity and resistance to temperature, corrosion and hot shock, and much more.
1. Graphite with excellent electrical conductivity, thermal conductivity.
2. Natural flake graphite powder is also a good lubricating additive powder.
1. As refractory material: graphite products with the properties of high temperature resistance, high strength, is mainly used to make graphite crucible in the metallurgical industry; graphite powder as ingot protection agent, metallurgical furnace lining in steel making commonly.
2. As conductive material: graphite powder used for manufacturing electrode, carbon brush, carbon rod, carbon tube,C, graphite gasket, telephone parts, television tube coating in electrical industry.
3. As wear-resistant lubrication materials in the mechanical industry. Lubricating oil often can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be in 200~2000 ºC temperature in a very high sliding speed, without lubricating oil work. Many conveying corrosive medium equipment, widely used graphite material made of piston cup, seal ring and bearing, they do not need to add lubricating oil when running.Graphite emulsion is also a good lubricant for many metal processing (wire drawing, drawing).

Graphitized Petroleum Coke is made from high quality petroleum coke under a temperature of 2800ºC.And,it is widely used as the best kind of recarburizer for producing high quality steel,special steel or other related metallurgical industries,because of its high fixed carbon content,low sulfur content and high absorb rate.Besides,it also can be used in plastic and rubber production as an additive.
Description:
Feature: High carbon, low sulfur, low nitrogen,high graphitization degree,high carbon98.5% with stable effect on improving the carbon content.
Application: Graphitized Petroleum coke is mainly used for metallurgy & foundry, it can improve the carbon content in steel-melting and casting, Also it can increase the quantity of scrap steel and reduce the quantity of pig iron, or use no scrap iron at all.
