Characteristic
Osmium is a chemical element with the symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element, with an experimentally measured (using x-ray crystallography) density of 22.59 g/cm3.
Phase at STP: solid
Melting point: 3306 K (3033 °C, 5491 °F)
Boiling point: 5285 K (5012 °C, 9054 °F)
Density (near r.t.): 22.59 g/cm3
when liquid (at m.p.): 20 g/cm3
Heat of fusion: 31 kJ/mol
Heat of vaporization: 378 kJ/mol
Molar heat capacity: 24.7 J/(mol·K)
Application
Manufacturers use its alloys with platinum, iridium, and other platinum-group metals to make fountain pen nib tipping, electrical contacts, and in other applications that require extreme durability and hardness.
