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.
  
  • As this metal does not absorb neutrons; It is used in nuclear power stations.
  • Its oxide is used in ultra strong ceramics. It is also used in manufacturing Crucibles.
