Flake graphite is assumed to be derived from the fine-grained sediments rich in organic matter. As metamorphic grade increases, carbonaceous material converts to micro-crystalline graphite [1, 3]. Based on the size of the crystal flakes, flake graphite is classified and graded according to their graphitic carbon content and particle size.
Expandable Flake Graphite. Expandable Flake Graphite Intercalation: Expandable flake graphite, also known as intumescent flake graphite, or simply "expandable flake", is a form of intercalated graphite. Intercalation is a process whereby an intercallant material is inserted between the graphene layers of a graphite crystal or particle.

Characteristic of natural flake graphite: Graphite is a carbon group element and a crystal of carbon element. According to the different crystallinity of graphite, it can be divided into crystalline graphite (flaky) and cryptocrystalline graphite (earth graphite) in industry.
Another interesting observation was the comparison between the evolution of R1 and R2 in the low-crystalline graphite flakes (disordered graphite); the R1 intensity ratios (0.65–0.90) and R2 peak area ratios (0.44–0.48) showed higher values than those obtained for the somewhat high-grade crystalline graphite flakes in the former samples.
