The metal is lustrous, bluish white, extremely hard and brittle even at high temperatures. It has the highest melting point and lowest vapour pressure of the platinum group metals. The metal is very difficult to fabricate but can be sintered in a hydrogen atmosphere at a temperature around 2000°C.

The solid metal is not affected by air at room temperature but the powdered or spongy metal slowly gives off osmium tetroxide, which is a powerful oxidising agent, and has a strong smell. The tetroxide is highly toxic and boils at 130°C.
