More than 200 applications
Thanks to its many properties, Graphite lends itself to multiple applications. Despite being a semimetal with great strength and natural rigidity, graphite is also light and benefits from a density of 2.09-2.23g/cm3. Its high sublimation temperature of 3,652 C allows it to play an important role in the metallurgical industry, standing above other metals that yield faster to heat. Because it is insoluble and hydrophobic due to its carbon structure, graphite easily separates from water. Finally, graphite is the only electrically conductive non-metallic mineral and, moreover, its conductivity is high for both electricity and heat.
MAIN APPLICATIONS IN
Refractory bricks: Resistant to high temperatures, refractory bricks are made of graphite, among other components, because of its exceptional heat resistance. They are used in the manufacture and refitting of furnaces and ovens, boilers, burners and fireplaces among others. Depending on their use and strength, refractory bricks are used in crematories, ceramics, steel, and metallurgical industries, etc.
Molds and molded parts: Graphite can wisthstand the heat of molding and wielding at very high temperatures. Its lubricating properties facilitate demoulding of parts when the interior of the molds has been treated with a thin layer of water and graphite based paint.
Other applications include: Crucibles, carbon additives, molten metal, high temperature lubricants, metal powder; alloys.
Lithium-ion batteries: Graphite is a critical component of lithium-ion batteries and can not be economically substituted. With the increasing demand for electric vehicles, the production of lithium-ion batteries must follow the same growth rate, which greatly increases the demand of graphite for their manufacture.
Virtually all commercial lithium-ion batteries use graphite since up to 15 times more graphite than lithium is needed in their manufacture. Each electric vehicle battery requires 50kg of graphite on average.
Fuel Cells: A fuel cell makes it possible to produce energy through chemical processes. Its refilling is sometimes necessary and the fuel then contains graphite. These batteries are used to power forklifts, buses and fuel cell vehicles.
Other applications include: alkaline and lithium batteries, flow batteries, and electric brushes.
