Question

What are the major applications for osmium? Is there any significant demand for this metal?

Answer

Osmium is a very dense, hard metal, and is used in high-friction applications such as fountain pen tips, instrument pivots, and electrical contacts.

Osmium in powdered form readily oxidises in air to form the toxic osmium tetroxide, which is used in the detection of fingerprints and as a forensic stain for microscope slides.

Osmium is also used in catalysis for chemical processes.
