Graphite exists as one of the massive covalent structures in nature. It unearths its programs as a lubricant or an inhibitor in nuclear reactors. This Buzzle lists the physical and chemical properties of this element.
TAGGED UNDER: Minerals

Graphite is an allotrope of the chemical detail carbon and is denoted via the symbol ‘C.’ Natural graphite happens in 3 wonderful forms inside nature – crystalline, amorphous, and lump graphite. The countries exporting this element are China, India, Brazil, North Korea, and Canada.

Lump graphite, also called vein, is determined all over the international; however, commercially mined handiest in Sri Lanka. This detail is grayish-black to steel gray in the shade and may mark impressions on the substrate. Because of this marking property possessed utilizing graphite, it is used to manufacture pencils and receives its name from the Greek word ‘graphene’ because of this ‘to write.’ Its bodily and chemical properties make it a unique chemical substance.

Physical Properties

Following are a number of the homes of this compound based on its structure and prevalence in nature.

Physical State

The mineral graphite is metallic gray to black in the shade and is odorless. It is opaque and has a sub-metallic luster. It is thought to have a completely smooth and greasy texture. It may be damaged effortlessly and leaves a black streak on the hand when touched. Although graphite is gentle and bendy, it isn’t elastic in nature.
Structure

This element is crystalline in nature; however, perfect crystals of graphite are not often located. The carbon atoms in their shape are arranged hexagonally in a planar, condensed ring device. This offers the graphite crystals a hexagonal form. Different layers of this element are stacked collectively and held by way of vulnerable covalent forces to shape a massive covalent shape.

Melting Point

Graphite has an excessive melting point above 3000ºF, similar to a diamond―the alternative allotrope of carbon. Hence, it’s far strong over an extensive range of temperatures.
Density

There is lots of vacant space among the graphite sheets held by the vulnerable covalent bonds, and the density of graphite is 2.09 to 2.33 g/cc, which’s lower than that of the diamond. The measured particular gravity of this detail is approximately 2.26 g/cc. However, it depends upon the purity of graphite. Graphite with a better ash content indicates a selected gravity higher than 2.26, whilst its herbal shape has a lower unique gravity or density due to the trapped porosity.
Solubility

Graphite is insoluble in water as well as other natural solvents. There are no attractive forces between the solvent molecules and the carbons atoms in its shape, and accordingly, it fails to dissolve in any of the natural solvents.
Electrical Conductivity

There is a massive delocalization of electrons inside the carbon layers of graphite. The delocalized electrons are unfastened to move and can conduct energy, accordingly, making graphite an excellent conductor of strength.

Chemical Properties

➤ Graphite is chemically inert to almost all chemical compounds.

➤ It burns completely while heated in oxygen to shape carbon dioxide. However, it fails to burn in the air, even though it is heated to high temperatures.

➤ When heated in the presence of focused sulfuric acid and potassium dichromate, graphite gets oxidized to carbon dioxide.

➤ Due to its chemical inertness and balance at excessive temperatures, it’s far broadly used as a refractory cloth.

Uses of Graphite
