Tungsten carbide (WC) exhibits a combination of bonding types. The bonding between tungsten (W) and carbon (C) atoms has significant covalent character, contributing to its extreme hardness and high melting point. Metallic bonding is also present between the tungsten atoms, contributing to properties like electrical conductivity. Due to the electronegativity difference between W and C, there is also a partial ionic character in the W-C bond, although it is less significant than the covalent and metallic components.
Which type of bond is present in superhard material tungsten carbide?
