Abstract

A comparative study was undertaken into the calcination conditions for the solid-state synthesis of pure Y1-xYbxBa2Cu3O7-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 Y1-xYbxBa2Cu3Oy 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, Yb)BaCuO.
