You can make several different forms of things out of graphite, such as graphite lubricants, brake linings, refractories and also in steelmaking. This mineral is known to have so many uses, which makes it the most perfect raw material for various goods. What actually is graphite?
Graphite is a mineral that is regarded as the most stable carbon type there is. Because of this variation, it is used as the basis when determining the heat of formation of different carbon compounds. It is one of the allotropes of carbon, which also includes diamond, amorphous carbon, lonsdaeleite, buckytube, plus three more.
Natural graphite comes in three primary types:
1. Amorphous graphite - this form is the product of coal's thermal metamorphism. It is available in the form of fine particles. It is also referred to as meta-anthracite.
2. Flake graphite - this type is also known as crystalline flake graphite. It is often plane and has hexagonal, angular or improper corners.
3. Vein graphite - this form is also termed lump graphite. It resembles a huge bunch of fibrous crystalline aggregates and is generally found in fissure fractures and veins. It is believed to be generated hydrothermally.
Graphite has numerous properties that make it recognizable from any other minerals and alltropes of carbon. To start with, if you look at its atoms in a microscopic level, its atoms have the shape of a hexagonal lattice with a fixed space between the planes. Second, it is capable of conducting electric power because its carbon deposits are strongly electron delocalized. Third, it has got thermal and sound abilities. Finally, it has remarkable dry lubricating and self-lubricating characteristics, making it preferred in many industries.
Graphite may be original or manufactured. Natural graphite is generally being used to make steel, rafractories, expanded graphite, foundry facings lubricants and also graphite lubricants. Synthetic graphite, on the other hand, is generally used in electrodes, neutron moderator, powder and scrap, along with RCCs or reinforced carbon-carbon products, like gold clubs, pool cue sticks, fishing rods, and cycle frames.
Around the world, there are several graphite mining quarries and areas. In Sri Lanka, there is an underground area where lump or vein graphite can be mined. Machineries and products like bulldozers are used to dig through the ore and remove the graphite.
To be able to get graphite and manufacture it to produce various goods, different methods and techniques are being used. Of course, tools and machines are also a necessity to make everything easier and faster.
