Uses
Uses & Benefits
  • Actinium metal has a great source of alpha rays but it is hardly used outside research purpose.
  
  • Alloys of Rhenium are used as an electric contact material. It can resist withstand arc corrosion.
  • Its catalysts are used in hydrogenation of fine chemicals. Its Alloy with nickel is used to produce turbine blades.
