Characteristics of graphite that make it indispensable in industries

Graphite is one of the allotropic forms of carbon and a fairly common mineral. It consists of carbon atoms in hexagonal structures that form layers. Due to its characteristics and properties, this material is widely used in the industrial sector.

Characteristics of graphite that make it indispensable in industries

Graphite is one of the allotropic forms of carbon and a fairly common mineral. It consists of carbon atoms in hexagonal structures that form layers. Due to its characteristics and properties, this material is widely used in the industrial sector.

It can be obtained naturally from open-pit or subway mines, or synthetically from an organic precursor, which can be derived from coal or petroleum.

Natural graphite is produced from the metamorphic recrystallization of organic matter found in rocks.

To produce synthetic graphite, a coal or petroleum derivative must be carbonized at high temperatures (1000°C) and the coke obtained is then graphitized at temperatures above 2500°C.

What are the characteristics of graphite?

Because it is a good conductor of electricity, natural graphite is often used in the electrical field, however, its applications are many.

Also, graphite is resistant to most acids, bases and corrosive agents, especially oxygen, tellurium, selenium and sulfur.

  • Batteries. Graphite is commonly used in dry zinc-carbon, rechargeable lithium-ion and alkaline batteries. This is due to the fact that this material adheres to manganese dioxide and achieves better conductivity.
  • Automotive and metal-mechanic sector. It is used for the production of brushes for motors, filling of gaskets and bearings, replacement of asbestos in the production of brake linings, etc.
  • Coating. By mixing graphite with clays it can be applied as a coating to clean the mold of metal castings, as well as to coat brakes and clutch in a car.
  • Pencil lead. When mixed with a paste, graphite is used in the lead of school pencils and pencils of all types.

It can be used as a solid lubricant as, for example, it lubricates brake shoes on train wheels. It is also a component in the manufacture of paints.

Likewise, synthetic graphite has characteristics that make it indispensable in industries.

  • Nuclear reactors. Today ultrapure graphite is used to moderate neutrons and reduce the action of uranium neutrons.
  • Aerospace industry. It can function as a thermal insulator and is used for the manufacture of blast tubes, rocket nozzles, conical noses, etc.

Artificially obtained or naturally occurring graphite is also used to increase the carbon content in steel and for the casting process, as well as in cast iron molds and crucibles.
