WebWell-known forms of carbon include diamond and graphite. In recent decades, many more allotropes have been discovered and researched, including ball shapes such as buckminsterfullerene and sheets such as graphene. Larger-scale structures of carbon include nanotubes, nanobuds and nanoribbons. WebAlthough graphite and diamond have the same chemical composition, their different crystal structures give them very different physical characteristics. For example, diamond is one of the hardest known substances, while graphite is one of the softest. Diamonds are typically clear, make excellent abrasives, and are good electrical insulators.
