Abstract : An article comprises an oriented thick film superconducting coating on a polycrystalline substrate. The coating includes at least two highly oriented platelet components of Bi(a)Sr(b)Ca(c)Cu(d)O(x)(BSCCO) wherein, in one component, a is 2, b is 2, c is 1, d is 2, and x is 8 and, in another component, a is 2, b is 2, c is 0, d is 1, and x is approx. 6, oriented such that said BSCCO platelets are essentially parallel to said substrate. Suitable polycrystalline substrates are MgO and alumina and mullite.
