Product Description

The Graphite Crystal has a hexagonal planar layered structure composed of carbon elements. The carbon atoms in the plane plane are strongly covalently bonded, and the layers are combined with van der Waals forces, which are very weak and the interlayer distance is large. Therefore, under the appropriate conditions, acid, alkali metals, salts and other chemical substances can be inserted into the Graphite layer, and with the carbon atoms to form a new chemical phase - graphite intercalation compounds (Graphite Intercalation on Compounds, referred to as GIC ). This intercalation compound, when heated to the proper temperature, can be rapidly decomposed instantaneously to produce a large amount of gas that expands the graphite into a worm-like new material, i.e., Expanded Graphite, in the axial direction. This unexpanded graphite interlayer compound is expandable graphite.

As a new type of functional carbon material, Expanded Graphite (EG) is a loose porous worm material obtained by intercalation, washing, drying and high temperature expansion of Natural Graphite flakes. EG has the advantages of softness, compression resilience, adsorption, ecological environment coordination, biocompatibility, and radiation resistance of natural graphite in addition to the excellent properties such as hot and cold resistance, corrosion resistance and self-lubricating of natural graphite itself And other characteristics. As early as the early 1860s, Brodie natural graphite and sulfuric acid and nitric acid and other chemical reagents after heating, found the expansion of graphite, but its application in a hundred years later began. Since then, many countries have launched a research and development of expanded graphite, made a major breakthrough in scientific research.
Expanded graphite in case of high temperature can instantaneous volume expansion of 150 to 300 times, from the chip into a worm-like, so the structure is loose, porous and curved, surface area expansion, the surface can improve the adsorption of graphite strength, This increases its softness, resilience and plasticity.
