is graphite a pure substance homogeneous mixture or a

pure substance. graphite is an allotrope of carbon similar to nanotubes diamond "buckyballs" and so on . graphite is composed of sheets of hexagonal rings of carbon. these individual sheets are very strong with good bonds. however there is little bonding each layer together- meaning graphite can be used as a lubricant and in pencils.
