Abstract

A comparative study was undertaken into the calcination conditions for the solid-state synthesis of pure Y_1-xYb_xBa₂Cu₃O_7-δ (x=0, 0.25, 0.5, 0.75, 1.0), the starting materials being Y₂O₃, Yb₂O₃, BaCO₃ and CuO. It was found that the calcination time should go up and the sintering temperature should lower, when the average rare earth ionic radius decreases. Moreover, the melting and the solidification temperatures of Y_1-xYb_xBa₂Cu₃O_y rise with decreasing Yb doping and increasing oxygen partial pressure, but depend only weakly on the particle size distribution. These deductions will be important to the fabrication of large-grain (Y, Y_b)BaCuO.
