Lead is available in several forms including ingots, foil, granules, ingots, powder, rod, shot, sheet, and wire. Small and large samples of lead foil, sheet, and wire (and lead alloy in ingot form) can be purchased from Advent Research Materials via their web catalogue.
Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air. Lead pipes bearing the insignia of Roman emperors, used as drains from the baths, are still in service. Alloys include pewter and solder. Tetraethyl lead (PbEt4) is still used in some grades of petrol (gasoline) but is being phased out on environmental grounds.
Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.
