Abstract
Superconducting Tl2CaBa2Cu2O8 with a Tc of 110 K was prepared by using the single-phase CaBa2CuO4 compound as the Ca and Ba source in the starting powder. Compared with the conventional method which uses CaO and BaCuO2 as the Ca and Ba sources, this new method enables a lower calcining temperature and/or a shorter calcining time for the formation of the 110 K superconducting compound. Since CaBa2CuO4 remains stable after being ground in methanol and hexane, this material is suitable for wet-processing prior to calcination. © 1988.
