Abstract
A new ceramic perovskite DyBa2SnO5.5 has been synthesized and develope d for its use as a substrate for Bi(Pb)-Sr-Ca-CuO superconductors. The dielectric constant and loss factor of this material are in a range s uitable for its use as a substrate for microwave applications. DyBa2Sn O5.5 is found to be chemically compatible with Bi(Pb)-Sr-Ca-CuO superc onductors. Bi(2223) superconducting thick film fabricated on DyBa2SnO5 .5 substrate gave a T-c(0)=110 K with a transition width of 2 K. (C) 1 994 American Institute of Physics.
