Natural graphite: what it is and its main uses

Natural graphite is a soft, gray to black mineral, crystallizes in a hexagonal system, heat resistant and is an excellent conductor of electricity. It is compressible and malleable, in nature it is found in small hexagonal crystals in the form of compacted, earthy, flaky, spherical aggregates.

Natural graphite: what it is and its main uses

Natural graphite is a soft, gray to black mineral, crystallizes in a hexagonal system, heat resistant and is an excellent conductor of electricity.

It is compressible and malleable, in nature it is found in small hexagonal crystals in the form of compacted, earthy, flaky, spherical aggregates.

Unlike diamond, graphite is very soft, although both have a carbon-based composition.

Physical and chemical characteristics of graphite

In nature, it is extremely abundant, due to its 80 to 90% carbon composition; however, to achieve a higher purity, further refining processes are necessary.

The aforementioned characteristics vary according to its geological location and its natural formation process.

Natural graphite comes in three forms:

ystalline flake graphite: Fnd in metamorphic rocks such as marble, quartz or mica, formed by small particles of flat plates. Composed of 70 to 96 % fixed carbon. It is used, among others, for the production of graphite and graphene foil.

orphous graphite: Fmed from rich hard coal sediments, it has some crystalline structure, but the crystallines are not well defined. Less than 85% of its composition is fixed carbon.

ystalline vein graphite: Cstallizes in the form of veins, its origin is due to the deposit of carbon in liquid or gaseous phase. Composed of 80% - 99% fixed carbon.

Some uses of natural graphite

1.- y lubricants. Ahough they are solids, they are used to reduce friction between two surfaces that slide between them. 2.- rging release agents.his type of graphite allows metals at high temperatures not to adhere to the molds and ensures the quality of the surface of each piece. 3.- illing muds. Ang the uses that this type of graphite can have is as a lubricant inside the drilling wells, to reduce the friction between the wall of the well and the drill pipe. 4.- ysical ground systems. Bmeans of natural graphite, "backfill" mixtures are formed for cathodic protection, which serve to maintain safety in electrical systems. 5.- rbon adjustment in smelting.o improve the properties of steel, an adjustment is made by adding graphite.
