The "lead" of the pencil is actually a mixture of graphite, clay and wax with a binder that seals the lead in the wooden shaft.

Two kinds of lubricant are used on a bicycle--oil and graphite.

Only oil of the best quality and pure graphite should be used.

But the project's principal investigator, at the materials science center of Trinity College in Dublin, says it can be done by mixing graphite with water and a surfactant, a form of soap, in an ordinary kitchen blender.

No graphite pencils, food, tobacco, chewing gum, lighters, matches, or pocketknives will be permitted inside the clean room.

Graphene is the first man-made two-dimensional material. It is actually only a one-atom-thick layer of pure carbon. It is closely related to nanotubes, and microscopic graphite balls called fullerenes.

Graphene is basically graphite, like the core of pencils, but its neatly-arranged and tightly-woven atoms make it 200 times stronger than a steel sheet of the same thickness.

Technical terms like ferrite, perlite, graphite, and hardenite were bandied to and fro, and when Paget glibly brought out such a rare exotic as ferro-molybdenum, Benson forgot that he was a master ship-builder, […]

Modern tennis racquets are made of graphite, fibreglass and other man-made materials.
