Theoretical resistance of an ionic crystal to destruction by an electric field
- 13 Downloads
We describe an electrostriction mechanism for destruction of an ionic crystal by an electric field. We present a simple theory that transforms into the well-known Rogowskii theory when there is no electrostatic breakdown. We show that electrostatic breakdown of the crystal lattice is due to separation of nearestneighbor ions with different charges to the point where the electric field exceeds the interionic attractive forces. The theoretical tensile strength of a crystal lattice undergoing electrostriction by an electric field is 15 MV/cm.
