Osmium powder is a kind of noble metal, which belong to platinum group. It is black powder, which tend to self-ignite and oxidize to osmium oxide. It has the largest density among all metals at present. Osmium metal powder is insoluble in cold water and ammonium hydroxide, just slightly soluble in nitric acid.

Applications
Osmium metal can apply to produce alloys of super high hardness. Its alloys with rhodium, ruthenium, iridium and platinum can be as bearing in instruments, tip of fountain pen and record player. Os-Pt alloy is for medical as bistoury. Os-Ir alloy can apply to pen, clock and other important instruments with long-life.
In industry, it uses as catalyst. It improve percent conversion at not very high temperature for sythesizing ammonia or adding hydrogen to react. Osmium powder can use in spectral analysis too.
