Preparation of a superconducting Tl2Ca2Ba2Cu3Ox thick film by processing a rolled Ca-Ba-Cu-O film in Tl2O3 vapor
Description
This patent describes a method for making a high temperature superconducting thick film. It comprises creating a Ba-Ca-Cu-O precursor thick film by rolling a nominal composition represented by the formula CaxBayCuuIv wherein: x is greater than or equal to 0.5 and less than or equal to 6; y is greater than or equal to 0.25 and less than or equal to 2; u is greater than or equal to 0.5 and less than or equal to 7.5; and x + y + u ≤ v ≤ x + y + u + 2 onto a substrate; and vapor evaporating Tl2O3 in flowing oxygen at atmospheric pressure onto the Ba-Ca-Cu-O precursor thick film and annealing the resultant thick film
