✦ Synopsis

By modeling the equilibrium state of the phase formation reaction of High-T, superconducting phase 1 : 2 : 3 (YBa2Cu30, -J and using the results of P-T-x correlation investigation of some authors, the variation of Gibbs free energy (dGm) versus temperature has been calculated. On the basis of the variation of AGm, 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, superconductors YBa2Cu,07-,.
