4 Uses
4.1 Uses & Benefits
  • Actinium metal has a great source of alpha rays but it is hardly used outside research purpose.
  • Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
  • It is also used as a catalyst in ethene polymerisation.
