Osmium crystals

History

Osmium was discovered in 1803 by English chemist Smithson Tennant in London. Chemists who studied platinum dissolved it in aqua regia to create soluble salts and observed a small amount of a dark, insoluble residue. Smithson Tennant analyzed the insoluble residue and concluded that it must contain a new metal. From the Greek word osme, meaning smell

DiscoverersSmithson Tenant
Discovery LocationEngland
Discovery Year1804
Etymology (Name Origin)Greek: osmê (odor).
PronunciationOZ-mi-em (English)
Even low concentrations in air can cause lung congestion, skin damage, or eye damage
Osmium is the least abundant stable element in the Earth's crust

Uses

Osmium is used alloyed with other metals in the platinum group to produce very hard alloys. Osmium alloys are used in the tips of fountain pens, instrument pivots, and electrical contacts Osmium tetroxide has been used in fingerprint detection and in staining fatty tissue for optical and electron microscopy. Used to tip gold pen points, instrument pivots, to make electric light filaments. Used for high temp. alloys and pressure bearings. Very hard and resists corrosion better than any other.

Sources

Obtained from the same ores as platinum.
