Carbon graphite: what it is, importance and uses

Minerals are elements widely used in everyday life. Their properties are very diverse and they have applications in different processes and industries. Graphitic carbon, or just graphite, is a very important element that stands out among others and has become the solution to problems within the industry.

Thanks to its characteristics and properties, carbon with graphite has a great importance and different uses in the industry. Without its application, we would not be able to perform many tasks or processes as we know them.

What is graphitic carbon and what are its properties?

Carbon graphite is a mineral element. Natural graphite usually consists of up to 90% fixed carbon, which is why it is called this compound. It is black in color, with a metallic luster and a greasy feel to the touch.

This element is very useful for being an excellent conductor of electricity at low temperatures and for having a high resistance to very high temperatures, in addition to having good stability to thermal expansion. With these properties, it can also behave as a semiconductor.

It also has a low coefficient of friction and can be used in both wet and dry environments. It is highly resistant to corrosion and abrasive chemicals.

What are the types of carbon graphite?

There are two types of carbon graphite, natural and synthetic. Natural carbon graphite is found in mines, while synthetic carbon graphite is created from a process called carbonization, where elements derived from petroleum enter.

Within each of these types of this element there are subtypes, such as crystalline flake, vein and amorphous graphite (natural); and isotropic and pyrolytic graphite (synthetic). Each of these has different applications, depending on their particular characteristics.

Where is graphitic carbon used?

This element has acquired great importance in different industries, such as metal-mechanical, electrical, chemical, pharmaceutical, petroleum, automotive, to mention a few. These are just some of the most common applications of graphite carbon:

  • Carbon graphite seals: It is used as a seal in mechanisms that need to maintain pressure or liquids without any type of leakage, such as mechanical shafts. Thanks to their resistance to chemicals and corrosion, they do an excellent job holding liquids and oils, withstanding friction and heat.
  • Crucible: These containers are designed for metal casting. The high temperature resistance and non-stick properties of graphite make it possible to melt different metals and reduce metal waste to a minimum. In addition, it is used as a tool to manipulate these containers.
  • Batteries: We can find this material in rechargeable lithium batteries, thanks to its benefits as a conductor and resistance to chemicals.
  • Electrical conductors: It is used as a semiconductor and as the main element of electrodes and resistors used in smelting furnaces and electrical circuits.
  • Lubricants: When used in powder form, this type of carbon works as an excellent dry lubricant, because it can enter and remain inside the precise mechanisms for their proper functioning. It is widely used in padlocks, locks and other mechanical elements.
