Uses

Uses & Benefits
  • Tin-niobium alloy is used for producing superconducting magnets.
  • Tin salt known as a tin II chloride, it is used as a mordant and as a reducing agent for dyeing calico and silk.
  
  • 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.
