Some Unknown Facts About Graphite

Graphite is the only non-metal that can conduct electricity. But did you know graphite is much more useful that we might know as it has helped us since early days like a pencil which contains graphite? Because graphite is resistant to heat and slows neutrons, it was used in the early years of nuclear-power research as a matrix to contain radioactive fuel elements and moderate their chain reaction.

Early atomic reactors were termed atomic piles because they consisted mostly of large piles of graphite blocks. Graphite is used not only in pencils but also as a lubricant for locksmiths and for bearings operating in a vacuum or at high temperatures. Because it is both conductive and slippery, graphite is used in generator brushes.
