Expanded graphite is a loose and porous worm-like substance obtained by intercalation treatment of flake graphite with strong acid and strong oxidant, and expanded at high temperature. A large number of network-like pore structures are formed inside it, with large specific surface area, high surface activity and strong Adsorption performance.

Petroleum coke can be used in different industries. Petroleum coke used in power plants and cement plants as fuel requires high calorific value and good abrasiveness. It is used by major factories and plays a key role.

Expanded graphite is a kind of loose and porous vermicompost prepared by graphite flakes through the process of intercalation, washing, drying and high temperature expansion.Insect-like substance. It can instantly expand its volume by 150-300 times when exposed to high temperature, changing from flake to worm-like.

Expandable graphite can be heated and expanded to form vermicular expanded graphite. The Franli factory uses low temperature and high temperature to study whether the properties of expandable graphite with different contents will change with the change of temperature.

The flake graphite is formed by high-pressure metamorphism，we will show you the purification methods and research progress of flake graphite.

Expanded graphite is a graphite product obtained by chemical treatment with natural flake graphite as raw material. It has good thermal conductivity, soIt is loose and porous, and also has the characteristics of being compressible, flexible and elastic. It does not deform or decompose under high temperature and high pressure. This stable chemical property brings it a wide range of uses.
