Characteristic
Tungsten borides are compounds of tungsten and boron. Their most remarkable property is high hardness. The Vickers hardness of WB or WB2 crystals is ~20 GPa and that of WB4 is ~30 GPa for loads exceeding 3 N.
WB2 has the same hexagonal structure as most diborides (AlB2, MgB2, etc.). WB has several forms, α(tetragonal), β (orthorhombic) and δ (tetragonal).
