2 Uses
2.1 Uses & Benefits
  • Aluminum is used in a various products; for example, cans, foils, kitchen utensils, window frames, beer kegs and aero plane parts, automobile parts, 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.
