Graphite
Definition:
(n.) Native carbon in hexagonal crystals, also foliated or granular massive, of black color and metallic luster, and so soft as to leave a trace on paper. It is used for pencils (improperly called lead pencils), for crucibles, and as a lubricator, etc. Often called plumbago or black lead.
Example Sentences:

(4) As subcritical crack velocities under cyclic loading were found to be many orders of magnitude faster than those measured under equivalent monotonic loads and to occur at typically 45% lower stress-intensity levels, cyclic fatigue in pyrolytic carbon-coated graphite is reasoned to be a vital consideration in the design and life-prediction procedures of prosthetic devices manufactured from this material.

(15) For some metals the analysis can be directly achieved by means of atomisation of the biological liquid in a flame or in a graphite furnace; for other metals it is necessary a treatment of the sample to separate the metal from the rest of the matrix, which can be: calcination, microcalcination, mining.
