- Osmium is a lustrous and silvery metal with an atomic number of 76 in the periodic table.
- It tends to be a dense metal. It appears like a bluish metal that occurs in the group Platinum.
- It is employed in industries as a catalyst.
- It also has a great use in the field of space applications because of its high reflectivity.
- It is used in light bulbs and incandescent lamps to increase the light output.
- It is also used in the field of fingerprint technology.
- It is used as an electrolyte in the battery applications as it can absorb hydrogen atoms.
- The metal is neither affected by acid or by water but tends to dissolve in molten alkalis.
- It is a naturally occurring element and it can also be obtained by commercial means during the refining of nickel.
- At high temperatures, the metal turns lustrous, hard and brittle.
- Osmium was first discovered in the year 1803 by William Hyde Wollaston and Smithson Tennant in England.
- Osmiridium and iridosmine are the ores of osmium and this metal is rarely found in some parts of North America, South America, and also in Russia.
