Facts
Interesting Facts
  • Thulium metal can resist corrosion due to dry air .
  • Only Tm-169 isotope of Thulium metal occur naturally.
  
  • Vanadium is a highly reactive metal, hence it is not found free in nature.
  • Vanadium can be found in almost 65 different types of minerals.

Uses
Uses & Benefits
  • Thulium metal produces isotopes that emits X-rays. This isotope is used in X-ray machine.
  • Thulium element is also used in Surgical equipment like laser.
  
  • 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.
