Geologic Importance of graphite

What is Graphite?

Well-formed crystals of Graphite are quite rare in nature, and most Graphite occurs in its massive form. It is a metallic mineral, black to dark gray, with a distinctive greasy feeling. This greasy nature reflects its internal crystal structure and many mineral properties. Graphite's extreme softness, greasy feel, low specific gravity, and the ease with which it leaves dark gray to black marks on paper usually distinguish it from similar-looking metallic minerals. Its name comes from the Greek word 'graphein' ('to write'), a reflection of centuries of use in writing and drawing. Graphite is produced by metamorphosing organic material originally deposited as sediment or mixed with sediment. As organic material is metamorphosed, hydrogen and oxygen are driven off as water, leaving the carbon behind to form Graphite. 


The Geologic Importance of Graphite

Graphite most often occurs in metamorphic rocks formed from regional metamorphism or contact metamorphism of organic-rich sedimentary rocks, such as organic-rich marble, quartzite, schist, gneiss, and metamorphosed coal. The sediment's original organic component provides the source for the carbon from which graphite forms. Coal is almost completely composed of organic carbon, so its metamorphism can produce large amounts of graphite-bearing rock. To a lesser extent, Graphite is also found in some igneous rocks, igneous veins, and pegmatites that are associated with metamorphosed graphite-bearing sedimentary rocks. As with the metamorphic occurrences, the graphite component of these igneous bodies is assumed to have originated from the associated organic-rich sediments. Much more rarely, Graphite also is found as small nodules in some iron meteorites. Crystals of Graphite are relatively rare and most often occur in marble. They may occur with pyroxene and spinel – two other minerals that also form from the metamorphism of organic impurities in limestone.


The Economic Importance of Graphite

Graphite's remarkably diverse properties allow it to be used in many ways. By volume, most of the Graphite mined in the United States is used to line the interior of furnaces or to make crucibles for use in high-temperature foundries since Graphite can withstand extremely high temperatures without melting. It's high melting temperature and insoluble nature also mean that large amounts of Graphite are used as lubricants and in manufacturing brake linings, alkaline batteries, and some paints. Because of its unusual crystal structure, Graphite exhibits many metallic materials' properties, such as its ability to conduct electricity. Consequently, Graphite is also used to produce electrodes and generator brushes.


Price of Graphite

Graphite particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Graphite. A large amount of large amount will be lower. The Price of Graphite is on our company's official website.
