2 Uses
2.1 Uses & Benefits
  • It has corrosion resistance and hence it is used to plate other metals.
  • Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
  • 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.
