2 Facts
2.1 Interesting Facts
  • 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.
  • Manganese is an essential trace element in all forms of life.
  • Manganese metal oxidizes very easily, but it does not fuse that easily.

3 Uses
3.1 Uses & Benefits
  • 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.
  • This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
  • Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
