Perforation and wetting of dielectric materials

Electrons distribute the energy they get in the electric field during their movements and create a belt vibration of the crystal lattice. Electrons that have reached a certain critical speed break off new electrons and break the equilibrium state, i.e., ionization occurs due to the impact of electrons in a solid body. This situation is observed in monocrystals with alkali-halide compounds and some polymers, and the values ​​of Et in a homogeneous (1) and non-homogeneous (2) electric field are different.

Electric breakdown of non-homogeneous dielectrics is observed in technical dielectrics with gas voids, and this process occurs very quickly, just like in homogeneous dielectrics. The electrical strength of dielectrics (glass, porcelain) placed in a homogeneous field does not depend on the thickness of the material. However, as the thickness of the dielectric increases, its composition changes, and as a result of the increase in the number of gas spaces, the electrical strength of the object decreases significantly. If the surface of the electrode is reduced, the number of defects in it will decrease due to the effect surface of the field, and the electrical strength of the dielectric will increase.
