Carbon - Structure of carbon allotropes Britannica
Graphite is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. … See more Natural graphite The principal types of natural graphite, each occurring in different types of ore deposits, are • Crystalline small flakes of graphite (or flake graphite) … See more In the 4th millennium BCE, during the Neolithic Age in southeastern Europe, the Marița culture used graphite in a ceramic paint for decorating See more Invention of a process to produce synthetic graphite In 1893, Charles Street of Le Carbone discovered a process for making artificial graphite.
