Abstract

The thermal stability of ceramic compounds RBa₂Cu₃O_z R=Y and Eu where Ba⁺⁺ is replaced by K⁺ is investigated here by TG analysis. The release of oxygen in RBaKCu₃O_z compounds starts at about 700° C, which is much higher than for undoped samples. Two major steps in the TG curves are observed for RBa_1.5K_0.5Cu₃O_z samples, corresponding to the oxygen-release temperatures of undoped and doped samples, respectively.
