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.
  
  • Yttrium Metal is highly toxic.
  • Yttrium Metal is highly reactive in nature hence not found free in nature.

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.
  
  • Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
  • It is also used as a catalyst in ethene polymerisation.
