Graphite, while as hard as a diamond, is also lightweight, soft and heat resistant due to its unique structural properties. It is one the most common non-metallic materials in the entire world. Graphite, also known as Plumbago during ancient times, was a non-metallic mineral. It is an allotrope of carbon and a semi-metal. Under normal conditions, graphite remains the most stable carbon form. In thermochemistry, graphite is used to determine the standard state for forming the heat in carbon compounds. Graphite can be regarded as the highest grade coal. Anthracite and meta-bituminous are the next two grades, but they are not typically used for fuels because of their difficulty to ignite.
This is an uncommon form of graphite
Carbon ranges from 85-98%.
There are four standard sizes: large, super large and fine
Graphite can be used for new technologies, including anode materials in lithium-ion batteries.
This is the most abundant type of graphite
Low carbon content 70-80%
Lowest purity
Useful for brake pads, gaskets, clutch materials, and pencil lead.
The only place where the mines are currently active is Sri Lanka
Limit the durability of most applications.

Types of Graphite
The three types of graphite that are found in various deposits can be divided into:Flake graphite
Flake graphite is a flat, hexagonal-edged plate. It can have irregular or angular edges if it does not break. Metamorphic rock, like limestone, gneiss or schist, contains it. It is evenly distributed throughout the ore or concentrated in crystallized pockets.This is an uncommon form of graphite

Amorphous graphite
Amorphous graphite consists of very small crystalline particles found in rocks such as slate, coal and shale. Carbon content varies depending on its parent material. It is found in coal as a result of the thermal metamorphism and is known as meta-anthracite. Because it is harder to burn than coal, it’s not used for fuel.This is the most abundant type of graphite
Low carbon content 70-80%
Lowest purity
Useful for brake pads, gaskets, clutch materials, and pencil lead.
Vein graphite (or lump graphite)
According to some scientists, vein graphite can be made from crude oils that are transformed into graphite by temperature and pressure. Riddle said that the veins “are very small, measuring between 5 to 10 centimeters” and are typically 70 to 99+ percent pure. It’s rare and expensive.The only place where the mines are currently active is Sri Lanka
