Top 23 interesting facts about Lead

  • Lead has been known since ancient time. Its name derives from the Greek word "protos" which means "first". Its symbol name derives from the Latin word "plumbum" which mean "lead".
  • Lead's melting point is at 327.5 C (600.65 K, 621.5 F) and its boiling point is at 1740.0 C (2013.15 K, 3164.0 F).
  • Lead is a soft, malleable, and very heavy metal.
  • Lead has a silvery-white-chrome color when melted, blue-white when it is freshly cut, and gray when exposed to air.
  • Lead is the heaviest nonradioactive element.
  • Lead is a poor electrical conductor.
  • Lead has a high corrosion resistance.
  • Lead reacts easily with organic chemicals.
  • Lead in powder form burns with a blue-white flame.
  • Lead has four stable isotopes: 204-Pb, 206-Pb, 207-Pb, and 208-Pb.
  • Lead is commonly found in ores with copper, zinc, and silver (mineral galena, cerussite, anglesite, etc).
  • Lead's annual production is about 10 million tones (a half from recycled lead).
  • Lead's main producers are Australia, China, the USA, and several others.
  • Lead is vastly used in car lead-acid batteries (more than a half of USA lead production is used in car batteries).
  • Lead is used in ammunition and shotgun pellets production, in ballast keel of sailboats, and in weight belts in scuba diving.
  • Lead is used as electrodes in electrolysis process and in high voltage cables.
  • Lead is used as shielding for radiation (in x-ray rooms) and as a coolant for lead cooled fast reactors).
  • Lead is also used in the walls and ceilings of sound proof rooms.
  • Lead has a significant importance with many uses in construction industry.
  • Lead is used as a coloring element in ceramic industry and PVC production.
  • Glass industry uses lead (lead oxide) to change the properties of glass.
  • Other lead applications include: in oil-based paints (discontinued in many countries), additive for aviation fuel, in candles for longer and even burn, in semiconductors for photo-voltaic cells, in infrared detectors, and few other niche applications.
  • Lead is poisonous for humans, particularly for nervous system.
