中文摘要	The phase formation, solid solution range and the substitution of La for Ba in La1+zBa2-zCu3Oy(La123) system are investigated systematically for obtaining and understanding the optimum condition to prepare La123 superconductors with higher Tc. The solid solution ranges ofLa(1+z)Ba(2-z)Cu(3)O(y) are z=0.20-0.70 in air and z=0 in N-2. Atmosphere of air or O-2 is favourable for the substitution of La for Ba. The substitution is suppressed when La1+zBa2-zCu3Oy are sintered and cooled in N-2. It is found that sintering and cooling procedure in N-2 atmosphere is one key procedure to prepare single phase high-quality LaBa2Cu3Oy superconductor with higher Tc.
