Expandable graphite crystal is a typical layered carbon material. Other heterogeneous particles such as atoms, molecules, ions, and even atomic clusters are inserted into the interlayer of crystalline graphite by physical or chemical methods to form a new layered compound, which is called graphite interlayer compound, namely expandable graphite.

Expandable graphite, refers to the appropriate conditions, acid, alkali metal, salt, and other chemical substances can be inserted between graphite layers, and carbon atoms combined to form a new chemical phase — graphite interlayer compound, this graphite interlayer compound is expandable graphite. This interlaminar compound, when heated to the right temperature, breaks down instantly and rapidly, producing a large amount of gas that causes the graphite to expand along its axis into a new, worm-like substance called expanded graphite.
Expandable graphite is heated at a high temperature can rapidly expand, expansion ratio as high as dozens of times to hundreds or even thousands of times, after the expansion of the graphite apparent volume up to 250 ~ 300 ml/g or bigger, after expansion of vermicular graphite present, size between zero a few millimeters to a few millimeters, in the internal network with a large number of unique microporous structure, called the expanded graphite or graphite worms. In addition to the excellent properties of natural graphite itself, such as heat and cold resistance, corrosion resistance, and self-lubrication, expanded graphite also has softness, compression resilience, adsorption, ecological environment coordination, biocompatibility, radiation resistance, and other characteristics that natural graphite does not have.
Expandable graphite and its expanded graphite can be used in iron and steel, metallurgy, petroleum, chemical machinery, medical, aerospace, atomic energy, and other departments, the application field is very wide.
