Product Description

OSMIUM CAS 7440-04-2 Os rare metals , Heavy platinum group metals




Osmium is known to be the most dense metal, with a density of 22.59g/cm3, a melting point of 3045 ℃ and a boiling point above 5300 ℃. Hexagonal dense lattice. Gray blue metal, hard and brittle, put in the iron mortar, it will easily become powder, osmium powder is blue black, and osmium metal powder can self ignite. Osmium vapor is highly toxic, can strongly stimulate the human eye mucous membrane, when serious, can cause blindness.

It can be made into target, bar, particle, wire or processed according to customer's requirements.




Melting point 3045 °C(lit.)
Color Gray blue



Osmium can be used as catalyst in industry. If osmium is used as catalyst in ammonia synthesis or hydrogenation, high conversion rate can be obtained at low temperature. If a little osmium is added to platinum, an osmium platinum alloy scalpel with high hardness and sharp edge can be made. Osmium iridium alloy can be made by using osmium and a certain amount of iridium. For example, the small silver dot on the tip of some advanced gold pens is osmium iridium alloy, which is hard and wear-resistant, and can be used as the bearing of clocks and important instruments, with a long service life.
