A systematic perturbation theory for high-density quark gas is developed. The ground-state thermodynamic potential is evaluated up to the second order in the Gell-Mann--Low coupling ..cap alpha../sub s/(M). Phenomenological analysis of the resulting equation of state suggests that the neutron-quark matter phase transition occurs at neutron matter densities n/sub B/ < 2 baryon/fm/sup 3/ provided 0.2 < ..cap alpha../sub s/ (3 GeV) < 0.3. The result supports the conjecture that superheavy steller objects may exist in the quark rather than in the neutron phase. The production of quark matter in heavy-ion collisions is also discussed briefly.
