  The phase diagram of the quark-gluon matter evolution is presented for the
SU(3)-model with a new phase of heavy deconfined quarks which exists in a
rather wide range of temperatures and densities. Fitting the chiral phase
transition data to fix the model parameters we establish another
(deconfinement) phase transition which separates a new phase from hadronic
matter. The parameters and properties of the phase diagram are discussed in
comparison with lattice and other results.
