Webb12 apr. 2024 · Hardness is also influenced by factors that are intrinsic to the bonding environment within the unit cell. In covalent crystals, this intrinsic hardness arises from the strong and directional covalent bonds and many models have been proposed to estimate this quantity [ 3, 4, 5 ].
