Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Osmium borides are compounds of osmium and boron. Their most remarkable property is potentially high hardness. It is thought that a combination of high electron density of osmium with the strength of boron-osmium covalent bonds will make osmium borides superhard materials. This has not been demonstrated yet. For example, OsB2 is hard (hardness comparable to that of sapphire), but not superhard. Osmium borides are produced in vacuum or inert atmosphere to prevent formation of osmium tetroxide, which is a hazardous compound.
