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.
- Iridium has an anti corrosion properties and it is used in special alloy with Osmium metal and that alloy is used in pen tips and compass bearings.
