2 Facts
2.1 Interesting Facts
  • Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
  • The leading producers of Zinc metal are Australia, Canada, China, U.S.A and Peru.
  • Naturally occurring minor elements include Cadmium.
  • Cadmium is released into atmosphere to control volcanic eruption and forest fires.
  • It is used for electroplating of Steel for corrosion resistance.
  • It can absorb neutrons and used in nuclear reactor to control atomic fission.

3 Uses
3.1 Uses & Benefits
  • It is mainly used for Galvanizing other metals.
  • It is also used for manufacturing die-casting and it is very essential for automobile industry.
  • It has very limited uses as it is a toxic metal and it can cause birth defects, cancer, etc.
  • Almost 80% of Cadmium metal is used in Nickel cadmium Batteries and now it is getting replaced with nickel hydride.
