three forms of graphite are flake crystalline and cryptocrystalline

Carbon Wikipedia

Today, smaller deposits of graphite are obtained by crushing the parent rock and floating the lighter graphite out on water. There are three types of natural graphite—amorphous, flake or crystalline flake, and vein or lump. Amorphous graphite is the lowest quality and most abundant.

20 Interesting Facts About Graphite Brian D. Colwell

May 05, 2019· Natural graphite is subdivided into three types of material: Amorphous, Flake, and High Crystalline. Crystals of graphite are relatively rare and most often occur in marble. Because graphite is resistant to heat and slows neutrons, it was used in the early years of nuclearpower research as a matrix to contain radioactive fuel elements and moderate their chain reaction.

Graphite

Crystalline flake graphite consists of isolated, flat, platelike particles with angular, rounded, or irregular edges. It is usually found in layers or pockets in metamorphic rocks. In some deposits, the flake graphite occurs as massive accumulations in veins, lenses, or pods. Amorphous graphite is formed by the thermal metamorphism of coal.
