Superhard Diborides News ChemistryViews

Superhard materials such as diamond are useful in many industrial applications.They are defined by hardness values larger than 40 GPa. One such material is rhenium diboride (ReB 2), which contains corrugated layers of covalently bonded boron and reaches hardness values of up to 40.5 GPa.Tungsten boride, in contrast, contains both corrugated and planar boron layers and is not superhard.
