Graphite is a form of pure carbon that normally occurs as black crystal flakes and masses. It has important properties, such as chemical inertness, thermal stability, high electrical conductivity, and lubricity slipperiness that make it suitable for many industrial applications, including electronics, lubricants, metallurgy, and steelmaking.
For instance, diamond is the hardest mineral, but graphite is one of the softest. Diamond is usually transparent, but graphite is opaque. Also, diamond is often used as an abrasive, whereas graphite makes a good lubricant. Graphite is an excellent conductor of electricity, while diamond makes a good electrical insulator. Uses of graphite
A mineral form of the element carbon. Hexagonal crystals or thin leaf-like layers. Steel-gray to black with a metallic luster and a greasy feel. An electrical conductor. Used for high-temperature crucibles, as a lubricant and in lead pencils.

The mineral graphite is often used as A a lubricant B an abrasive C a source of iron D a cementing material. a lubricant. Quartz and halite have different crystal shapes primarily because. of the internal arrangement of the atoms. Which property is most useful in mineral identification.
Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500 C Figure 1-4. The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.

Jun 05, 2019 Mineral Notes Graphite. 5 June, 2019. This article was written by Executive Consultant, Andrew Scogings. Graphite is an allotrope of carbon and is grey to black, opaque, very soft, has a low density and a metallic lustre. It is flexible and exhibits both non-metallic and metallic properties, making it suitable for diverse industrial applications.
Graphite. Graphite is a single element crystal composed solely of carbon, and thus is a polymorph of diamond. Like diamond, graphite is a completely covalent mineral, however, here the structure is isometric with tetrahedral symmetry. Each carbon atom is surrounded by three other carbon atoms in 3-fold planar coordination due to the sp2 ...
Graphite is like diamond, It is a form of native carbon crystalline with its atoms arranged in a hexagonal structure that is opaque and dark gray to black.It occurs as hexagonal crystals, flexible sheets, scales, or large masses. It may be earthy, granular, or compact. Graphite forms from the metamorphism of carbonaceous sediments and the reaction of carbon compounds with hydrothermal solutions.
