Description
We extend the instanton model of the QCD vacuum with quark-induced interactions to nonzero temperature. Using the mean field approximation, we compare the free energies of the two phases, the ''polymer'' and ''molecular'' ones. We have found that the phase transition should occur in a narrow temperature interval around 200 MeV. (orig.)
