What Is a Break Key?

Broken bond refers to that when the atoms on the surface of the mineral crystal and the fracture surface are separated from each other, the chemical bond between them is broken, and the ions on the surface have unsaturated chemical bonds, which is called broken bond. The nature of the ions that produce the broken bond is different from the ions inside the crystal, and the original valence electrons can still be bonded to other ions. Surface breaks cause excessive surface charge and energy imbalance on the mineral, which makes its surface chemical properties different from those in the crystal. ^[1]
