three forms of graphite are flake


There are three principal types of natural graphite, each occurring in different types of ore deposit: Crystalline flake graphite (or flake graphite for short) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken and when broken the edges can be irregular or angular. It has a distinctive plate like or flake formation.

Graphite is a soft, black, lustrous mineral composed of carbon in a hexagonal crystalline structure. It is found in three different forms: in high-grade metamorphic rocks as disseminated crystal flakes; in veins or fractures as vein graphite; and in thermally metamorphosed coal deposits as amorphous graphite.

Graphite is a stable form of naturally occurring carbon, also known as plumbago, blacklead or mineral carbon. Graphite is mostly used for refractory, battery, steel, expanded graphite, brake linings, foundry facings, and lubricants. Graphene, a naturally occurring ingredient in graphite, has unique physical properties and is one of the strongest known substances.

Depending on the mode of occurrence and origin, graphite is graded into three forms: flake, crystalline (lumpy) and cryptocrystalline (amorphous). In nature, graphite is usually found in mechanical association with feldspar, mica, quartz, pyroxene, rutile, pyrite and apatite. Common Graphite Issues

Flake graphite can be found as a lamellar or flaky shape in certain metamorphic rocks such as limestone, gneiss, and schists. flotation is used to extract flake graphite. "Floating" graphite has a graphite content of 80% -90%. More than 98% of the layer was made using graphite chemical preparation processes.

Flake Graphite Flake graphite forms when carbonaceous material is subjected to high-grade metamorphism. This type of graphite has a higher carbon content than amorphous graphite and typically forms in flakes or plates. The size, shape, and purity of the flakes vary depending on the conditions under which the original material was metamorphosed.

It is found in metamorphic rocks — such as limestone, gneiss and schist — and is distributed uniformly throughout the body of the ore or in concentrated, lens-shaped pockets.

Within the flake category, there are three main grades: large (+80 mesh), medium (+100-80 mesh) and fine (-100 mesh). More recently, some non-Chinese producers have started to market what they refer to as "jumbo" flake graphite (+50 mesh). Spherical graphite (99.9% C) is manufactured from fine flake graphite.

Actually, diamond is the hardest known mineral with a Mohs hardness scale of 10, while graphite is nearly the softest with a hardness of 1.5. Three main types of graphite are traded; crystalline, flake and amorphous (or non-crystalline). The crystalline grade is the most valuable and the amorphous the least.

Properties of flake graphite: it is flake, thin leaf crystalline graphite, and its size is generally (1.0 ~ 2.0) × (0.5 ~ 1.0) mm, maximum 4 ~ 5mm, sheet thickness 0.02 ~ 0.05mm. The larger the scale, the higher the economic value. They are mostly disseminated and gneissic distributed in rocks. It has an obvious directional arrangement.

Flake Graphite and Vein Graphite both form by precipitation of carbon in a high-temperature, high-pressure environment. Sources of the free carbon atoms might be magmatic, thermal decomposition of carbonates, or pyrolysis of organic matter. The free carbon is transported from the source to the location where it precipitates as a crystal.
