Facts
Interesting Facts
  • Luster of Indium is bright in nature.
  • Reich and richer were looking for thallium in zinc metal and they discovered Indium metal.
  
  • Osmium metal does not oxidize in air unless it is heated.
  • But if it heated den it forms Osmium Tetroxide, which is highly toxic.

Uses
Uses & Benefits
  • 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.
  
  • Its has very limited uses and its alloys are very hard and are used in the manufacturing of pen tips, pivots, needles and electrical contacts.
  • It is also used as industrial catalyst to speed up the chemical reaction.
