Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earthâs softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils. Even modern pencil âleadâ is composed of graphite mixed with clay.
Carbon is ordinarily classified as a nonmetal but has some metallic properties and is occasionally classified as a metalloid. Hexagonal graphitic carbon (graphite) is the most thermodynamically stable allotrope of carbon under ambient conditions. It has a lustrous appearance and is a fairly good electrical conductor.
