Graphite is an allotroph of carbon, gray black, opaque solid, melting point of 3652℃, boiling point of 4827℃. Solid carbon graphite block, a stable chemical property, is corrosion resistance, and is hard to react with acid, alkali and other agents. Carbon graphite block burns in oxygen at 687℃ to form carbon dioxide. It can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. The graphite carbon block also can be used as an antiwear agent or lubricant. High purity graphite as a neutron decelerating agent in the atomic reactor, can be used to manufacture graphite crucible, electrode, brush, dry cell, graphite fiber, heat exchanger, cooler, arc furnace, arc lamp, pencil core, and so on.

Graphite Blocks For Sale

  • EDM Graphite Block
    As China's manufacturing industry is moving towards high-end development, the country is vigorously promoting intelligent manufacturing. Therefore, in the field of precision mold manufacturing, the requirements for the discharge materials used in the processing are becoming higher and higher, so THE position of EDM graphite in the processing of these precision molds is becoming higher and higher, and the screening of EDM materials has been highly concerned by the industry.

  • Isostatic Graphite Block
    Isostatic graphite is made of high purity graphite and has isotropy. Isostatic graphite is a new carbon graphite block developed in the world in the past 50 years, which is closely related to today's high technology. It is irreplaceable for manufacturing single crystal furnaces, graphite crystallizer for metal continuous casting, graphite electrode for EDM, and also an excellent material for decelerating and reflecting materials of rocket nozzles and graphite reactors.

Properties and Characteristics of Graphite Blocks

Good Absorption
Thermal Conductivity
Chemical Stability
Oxidation and Reduction Effect
High Temperature
Lubricity
Good Absorption of Graphite Blocks
Good Absorption

Our graphite blocks for sale have good absorption. The void structure of carbon makes carbon has good adsorption, so carbon is often used as adsorption material, used to absorb water, odor, toxic substances, and so on.

Thermal Conductivity of Graphite Blocks
Thermal Conductivity

Carbon graphite block has good thermal conductivity, fast heat transfer, uniform heating and fuel saving. The baking dish and pot made of graphite are heated quickly, and the baked food is heated evenly and cooked from the inside out. The heating time is short, which not only tastes pure but also locks the original nutrients of the food.

Chemical Stability of Graphite Blocks
Chemical Stability

China graphite blocks have good chemical stability at room temperature and are not eroded by any strong acid, strong alkali, and organic solvents. Therefore, even if the long-term use of graphite products loss is very small, as long as clean as new.

Oxidation and Reduction Effect of Graphite Blocks
Oxidation and Reduction Effect

Graphite carbon block material has strong oxidation and reduction effect. In particular, graphite mattress can produce negative oxygen ions after heating, so that the activity of the surrounding articles, maintain human health, effectively prevent aging, make the skin full of luster and elasticity.

High Temperature of Graphite Blocks
High Temperature

Carbon in 2000-3300℃ high temperature environment after at least a dozen days and nights of graphitization process to become graphite, therefore, graphite products environmental health, no radioactive pollution, high temperature resistance.

Lubricity of Graphite Blocks
Lubricity

Carbon graphite block has good lubricity and is often used as a lubricant in mechanical production, in order to replace the lubricating oil that cannot be used under high temperature and high pressure.

How To Make Graphite Block?

  • Our OEM carbon graphite block mainly uses high-quality petroleum coke as raw material, coal asphalt, or synthetic resin as the binder.


  • Through the preparation of raw materials, ingredients, mixing kneading, pressing, crushing, remixing kneading, molding, many times of roasting, many times of dipping, purification and graphitization, machining, and made of graphite block.
