Graphite is one of the naturally formed polymorphs of carbon, just like diamond or coal. Thanks to its thermal and electrical conductivity, strength and stiffness the mineral is of use in various industries.

Positive features of graphite have been at first utilized by the steel industry in production of steel and heat-resistant materials. Thanks to its chemical resistance, 98% of the pure graphite is used for production of the graphite sealing plates which are effective everywhere where other materials don't fit, as for example under the condition of high temperatures in the chemical and metallurgical industry.

At the present time protection of the environment is the important aspect of our existence. While looking for alternative energy sources, graphite is the most convenient solution not only in production of lithium-ion batteries but it has also become irreplaceable in production of solar cells and semiconductors.

It found its place also in the car industry, not just as a part of brake-shoe linings, sealings and gears but also as the lightest material for bodyshell production, used by many renowned companies.
