PHONETICS

IDENTIFICATION

Osmium is a hard, brittle, bluish-white transition metal and is found as a trace element in alloys, mostly in platinum ores. Being the densest, naturally occurring element, with a density of 22.59 g/cm3, its alloys with platinum, iridium, and other platinum group metals are employed in fountain pen nibs, electrical contacts, and other applications where extreme durability and hardness are needed.
