Method for expanding forms lamellar graphite and resulting product.

a method for obtaining expanded graphite is presented from lamellar graphite flake comprising a first supply of particles lamellar graphite flake having a purity, then sandwiching particles lamellar graphite flake with an intercalation compound expandable graphite , following the expansion of the graphite intercalation compound to exfoliate the flake graphite particles to end the spray particles exfoliated graphite flakes for further delamination.
