Abstract

This paper reports on the results of four different wet chemical techniques used for the synthesis of superconducting oxides, YBa2Cu3O7 (YBCO). YBCO samples were prepared by complexion citric gel route (CT), acetate-tartrate sol-gel (ASG), oxalate/ethanol coprecipitation (COP), and acetate-tartrate sol-gel solid-state reaction (ASG-SSR) techniques. Each of the YBCO powders was annealed for 4 h at 880 °C, 900 °C, 920 °C, and 950 °C to find the optimum temperature. The optimum sintering temperature for the formation of Y-123 phase is very much dependent on the type of wet chemical technique used to prepare the powders.
