Dielectric catastrophe and insulator-conductor transition

The phenomenological conception of “dielectric catastrophe” applies to the explanation of dielectric-conductor transitions in metal hydrides, hydrogen, rare gases and alkali metals. This conception together with the simple cell model appears to be applicable for the hydrides, where it predicts the correct transition density. For the others substances it fails, but the cell models are still of use in the description of metallization.
