Graphite - A Marvel of Nature
Graphite, formed from the ancient sedimentary rocks of metamorphic origin, is known to the mineral world as a marvel of nature. Unquestionably, graphite is one of the most important industrial minerals, and is widely used in a variety of applications from fire and metal production to welding and ship building.
The formation of graphite is a result primarily of the force of water reacting with mica, feldspar and sandstone and creating what is known as a crystalline form of carbon, which we call graphite. Graphite stones are formed by a process called “metamorphism” where an originally homogeneous sedimentary rock is subjected to extreme heat and pressure, which in turn alters its composition and produces distinct patterns and layers of graphite. This process of metamorphism occurs over thousands of years and is recognized as the formation of graphite.
Graphite is divided into three main categories: flake, amorphous, and vein. Flake graphite is the most common form of graphite and is the most common form commercially mined. This type of graphite is found in large flat beds and is generally mined with great precision. Amorphous graphite is a form of graphite in which the crystals have not been established and is a less common form of graphite.Vein graphite is a unique form of graphite as it is constantly growing, developing, and differentiating itself, making it a very precious mineral.
Graphite’s physical and chemical properties attribute to its incredible qualities. It has a low density, high thermal and electrical conductivity, and is acid, alkali and corrosion resistant. These qualities make it extremely versatile, allowing for a variety of uses across a wide array of industries. Graphite is used in many everyday items such as pencils, lubricants and even packings for hydrogen fuel cells. Graphite also is used by the medical industry in the production of implants and prostheses due to its strong and lightweight properties.
Above all, Graphite is essential to the production of steel. In fact, it is estimated that as much as 70% of all graphite is used in steel production alone. This makes steel production one of the largest industries to rely on graphite. Graphite is used in the production of steel to improve strength, thermal and electrical conductivity, abrasion resistance and thermal shock resistance. It is even used in the production of stainless steel due to its superior corrosion resistance.
The uses of graphite are myriad and this ancient stone has earned its place in history as an important industrial mineral. Its many uses across a variety of different industries have earned it a reputation as a marvel of nature as it continues to surprise people with its unique properties and characteristics. For generations, graphite has been used to enhance the efficiency and durability of countless products, and this carbon derivative has solidified its place in the mineral world.
