    Graphite 101 | Focus Graphite, Graphite is the only non-metal element that is a good conductor of electricity and heat Its softness and streak make graphite useful in making lead for pencils Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flak It breaks into minute, flexible flakes that easily slide over one anotherwhat are the different types of coal what are their uses ,, Graphite The technically highest ranking coal, graphite is difficult to ignite, and is rarely used as a fuel It is mostly used in pencils, and as a lubricant in its powdered form Steam coal - also known as thermal coal - is mainly used in power generation Coking coal - also known as metallurgical coal - is mainly used in steel productionTypes of Graphite: Amorphous, Flake and Vein | INN, Graphite in this form is found all over the world, but is only currently mined in Sri Lanka Of the types of graphite it is considered the rarest Of the types of graphite it is considered the rarestVitrinite, Vitrinite is one of the primary components of coals and most sedimentary kerogensVitrinite is a type of maceral, where "macerals" are organic components of coal analogous to the "minerals" of rocksVitrinite has a shiny appearance resembling glass (vitreous) It is derived from the cell-wall material or woody tissue of the plants from which coal was formedCoal vs Graphite, As nouns the difference between coal and graphite is that coal is (uncountable) a black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel while graphite is an allotrope of carbon consisting of planes of carbon atoms arranged in hexagonal arrays with the planes stacked loosely that is used as a dry lubricant and in "lead" pencils.
