Facts
Interesting Facts
  • 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.
  
  • 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.

Uses
Uses & Benefits
  • 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.
  
  • It is mainly used for Galvanizing other metals.
  • It is also used for manufacturing die-casting and it is very essential for automobile industry.
