Norm‐conserving pseudopotentials derived from the Dirac equation serve for the derivation of new characteristic quantities. For each chemical element and each electron shell, two characteristic energy and two characteristic spacing quantities are calculated. Therefrom, functions are formed for binary compounds and alloys of type AB. If two each of these functions are plotted in pairs, an arrangement is obtained according to regions with crystals of the same structure type and same space group, of the same melting temperature class etc. This systematics enables one to eliminate unfavourable combinations in the search for specific physical properties. A few results are plotted.
