Uses

Uses & Benefits
  • Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
  • Its oxide is used as pigments for glass and ceramics.
  
  • It is a highly radioactive metal; and sometime Radium-223 is used to treat prostate cancer.
  • It is used in luminous paints.
