Graphite can be as hard and durable as diamond. However, its unique structure means that it is soft, light, and heat resistant. It’s one of the most popular non-metallic minerals. In antiquity, graphite used to be called Plumbago. It’s a semi-metal and crystal form carbon. Graphite is the stablest form of carbon under normal conditions. This is why graphite is often used in thermochemistry as it defines the normal state for the formation of heat from carbon compounds. Graphite might be the best-quality coal. The second highest is either anthracite (meta-bituminous) coal. But graphite can’t usually be used as a fuel, because it is hard to ignite.
The type and features of Graphite
There are three major types of natural graphite. Each one is found in different deposits.
Flake graphite
Flake graphite can be found as a single, flat-shaped, hexagonal, or plate-like particle with hexagonal edges. It may break if it doesn’t. If broken, edges can be irregular or angular. This mineral is found in metamorphic rock, like limestone, gegneiss, or schist. It can be evenly distributed within the ore body, or concentrated in crystallized pockets.
This graphite is rarer than the others.
Its range in carbon is approximately 85-98%.
There are four main sizes available: large, small, medium and fine.
Graphite for new technologies like anode materials in lithium-ion batteries
Amorphous Graphite
Amorphous graphite are very fine crystal particles that can be found within mesomorphic layers like coal, slate and shale. It depends on its parent material’s carbon content. If it’s found in coal, it results from thermal metamorphism. It is also known as meta-anthracite. This is a different kind of coal than other fuels. It’s not very easy to burn.
This form is far and away the most prevalent of graphite
Carbon-free, 70% to 80%
The lowest purity
This is used to make refractory brake pad, gaskets and clutch materials as well as pencil leads.
Vein graphite (or lump graphite)
Vein graphite can be thought to have been derived from crude oil reserves. This is then transformed into graphite with temperature and pressure. Riddle claimed that the veins were “very small,” measuring between 5-10 centimeters in diameter, and usually contain 70-99+ percent pure graphite. It’s rare and very expensive.
It is currently only found in Sri Lanka
