Top 11 interesting facts about Cadmium

  • Cadmium was discovered in 1817 by Fredrich Stromeyer. Cadmium's name derives from the Greek word "kadmeia" and the Latin word "cadmia".
  • Cadmium's melting point is at 320.9 C (594.05 K, 609.62 F) and its boiling point is at 765.0 C (1038.15 K, 1409.0 F).
  • Cadmium is chemically similar to zinc and mercury.
  • Cadmium is bluish-white, soft, malleable, resistant to corrosion, and ductile metal.
  • Cadmium is a byproduct of zinc production.
  • Cadmium's use is decreased due to its toxicity.
  • Cadmium is composed of eight naturally occurring isotopes, two of them are naturally radioactive (113-Cd and 116-Cd) and three of them are stable (110-Cd, 111-Cd, and 112-Cd).
  • Cadmium is a rare metal making up just 0.1 ppm of the Earth's crust.
  • Cadmium's top producers are China, South Korea, and Japan.
  • Cadmium is used in batteries, electroplating in aircraft industry, and a small amount in nuclear fission and different laboratory experiments.
  • Cadmium's use and supply in Europe is restricted due to its dangerous effects on environment and human health.
