What are the uses of the metal osmium?

Answer 1

Osmium, a platinum group metal, reacts slowly with atmospheric oxygen at room temperature giving to OsO4. On heating it burns. Bulk metal doesn't react with boiling aqua regia. Osmium powder reacts with nitric acid and boiling concentrated sulfuric acid. On heating osmium reacts also with fluorine, chlorine, phosphorus, tellurium etc. On melting with alkalies in the presence of oxidizing agents it turns into salts of osmic(VI) acid H2OsO4.

Answer 2

Osmium is used in alloys to make fountain pen tips, instrument pivots, and electrical contacts. It is also used in fine mechanical components, such as balance wheels and needles for record players, due to its hardness and resistance to wear. Additionally, osmium tetroxide, a compound of osmium, is used in biological staining and organic synthesis.

Answer 3

Osmium is used for record player needles, ball point pen tips, electrical contacts, and fountain pen tips.
