3 Uses
3.1 Uses & Benefits
  • Its alloys are used in spacecraft, aircraft and ammunition industry.
  • Its pipes are used in distillation plants, submarines, hulls of big ships, etc.
  • Rubidium's main application is in the glass manufacturing.
  • Rubidium can very easily get ionized and hence it is used for ion engines, but it is still less efficient than that of Caesium.
