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.
  
  • Manganese is an essential trace element in all forms of life.
  • Manganese metal oxidizes very easily, but it does not fuse that easily.

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.
  
  • This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
  • Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
