A semi-phenomenological method is developed for calculating binding energies and other characteristics of hypothetical superdense, finite-size nuclei assuming the volume parameters (equilibrium density and binding energy) of the superdense phase to be known. Introducing the energy density functional, the baryon density distribution is studied and the coefficient of surface tension for a superdense nucleus is calculated as a function of the volume parameters of the superdense phase. We construct a modified Weizsaecker formula and apply it to investigate the dependence of the binding energy of superdense nuclei on the baryon number A. It turns out that for any reasonable choice of the volume parameters of the superdense phase: 1) the system becomes bound when the number of baryons equals A/sub min/approx. =20--70; 2) metastability of normal nuclei with respect to the transition to the superdense state is possible only for A> or =100; 3) superdense nuclei with A = 300--400 are the most stable. The experimental search for superdense nuclei is discussed.
