By modeling the equilibrium state of the phase formation reaction of High‐ T c superconducting phase 1:2:3 (YBa 2 Cu 3 O 7− x ) and using the results of P ‐T− x correlation investigation of some authors, the variation of Gibbs free energy (Δ G m) versus temperature has been calculated. On the basis of the variation of Δ G m, the technology procedure of preparation of phase 1:2:3 with desired x has been established to meet requirement of basic investigation and application of High‐ T c superconductors YBa 2 Cu 3 O 7− x .
