Facts
Interesting Facts
  • The main source of Cobalt is as a by-product of copper and nickel metal mining.
  • Cobalt metal can be obtained from other elements like Oxygen, Sulfur and Arsenic.
  • It s also used in electroplating process as it exhibits anti cession properties.
  
  • 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
  • Its alloys with aluminum and nickel are used to make powerful magnets.
  • Few other alloys exhibit high-temperature strength and hence they are used in Turbines of Jet and Gas engine.
  
  • 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.
