The relations between the critical exponents of
basic stability characteristics
are obtained based on the thermodynamic stability requirements for the
generalized one-component system without engaging any hypotheses. The conditions are
obtained, where these relations are fulfilled as equalities. The outcomes are applied
to the consideration of critical properties of the isomorphic γ-α transition
in the metal cerium. It is shown, that for cerium the corresponding relations
are fulfilled as equalities. It is also shown, that the equilibrium curve in the P-T
phase diagram of cerium continuously passes into the lowered stability curve
in the supercritical region, that provides symmetry between its critical exponents.
The obtained results are in accord with the scaling law hypothesis without any
assumptions about homogeneous functions for the potentials.
Key words: stability coefficients, critical exponents, statical scaling law
hypothesis, phase equilibrium curve, quasispinodal
