Interesting Facts
- 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.
  
- Luster of Indium is bright in nature.
- Reich and richer were looking for thallium in zinc metal and they discovered Indium metal.

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 used to produce indium tin oxide (ITO), it is used in manufacturing touch screens, flat screen TVs and solar panels.
- Its nitride, phosphide and antimonide are used in transistors and microchips.
