We have fabricated films of the high Tc superconducting oxide YBa2Cu3O7 by screen printing on alumina, calcia-stabilized zirconia, yttria-stabilized zirconia, SrTiO3 and La2CuO4 substrates. Alumina was found to be a suitable substrate for screen printing. La2CuO4 and SrTiO3 substrates can be used with shorter annealing times. Superconducting transition temperatures in the vicinity of 85 K have been established in some of the films. © 1980.
