Abstract:	Barium erbium niobate (Ba2ErNbO6) has been developed as a new substrate for (Bi,Pb)(2)Sr2Ca2Cu3Ox, [Bi(2223)] superconductor film. Ba2ErNbO6 (BENO) has a cubic perovskite structure with lattice constant, a = 8.318 Angstrom. The Bi(2223) superconductor does not show any detectable chemical reaction with BENO even under extreme processing conditions. Dip coated Bi (2223) thick film, Ba2ErNbO6 substrate, gave a T-c (0) of 110 K and current density of similar to 4 x 10(3) A CM-2 at 77 K and zero magnetic field.
