Facts
Interesting Facts
  • Major mining countries of Uranium include Russia, Australia, Namibia, Canada and Niger and total 33% Uranium are mine in Kazakhstan.
  
  • Bismuth metal is soluble and reacts with concentrated nitric acid.
  • It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.

Uses
Uses & Benefits
  • The main use of this metal include nuclear fuel which is used to generate electricity yin nuclear power stations.
  • Synthetic elements like transuranium are made from Uranium metal.
  
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
