Graphite: Properties, Occurrence and Applications

Graphite is a naturally occurring form of the element carbon (Element 6, symbol C). It is black to steel grey in colour, opaque, and with a distinctive soft lubricative texture [1]. Graphite exhibits two crystalline structures; hexagonal (alpha) and rhombohedral (beta). Both crystalline structures exhibit a high degree of anisotropy, which ...
