Osmium - 76Os: uses
The following uses for osmium are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses.
- almost entirely used to produce very hard alloys with other metals of the platinum group, for fountain pen tips, instrument pivots, and electrical contacts
- OsO4 is used to detect fingerprints and to stain fatty tissue for microscope slides
- platinum/osmium 90/10 alloy is used in implants such as pacemakers and replacement valves
