Production
As a new functional carbon material, Expanded Graphite (EG) is a
kind of loose porous wormlike substance obtained by natural
Graphite scales through intercalation, water washing, drying and
high temperature expansion. EG in addition to the natural graphite itself cold and heat
resistance, corrosion resistance, self-lubrication and other
excellent properties, but also has natural graphite without
softness, compression resilience, adsorption, ecological
environment coordination, biocompatibility, radiation resistance
and other characteristics.
Brodie discovered expanded graphite in the early 1860s by heating
natural graphite with chemical agents such as sulfuric and nitric
acid, but its application did not begin until a hundred years
later. Since then, many countries have launched the research and
development of expanded graphite and made a significant
breakthrough in scientific research.
Expanded graphite in high temperature can be instant volume
expansion 150~300 times, from flake into vermicular shape, thus
loose structure, porous and bending, surface area expansion,
surface can improve, adsorption flake graphite force enhanced,
vermicular graphite can be inserted between themselves, so as to
increase its softness, resilience and plasticity.
