3 Uses
3.1 Uses & Benefits
  • Uses of Scandium are limited to research purpose only. However, it has very low density and higher melting point.
  • Its compounds like scandium iodide is used in mercury vapor lamps to produce very bright white light.
  • 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.
