ABSTRACT:
A superconducting screen printing ink comprises an organic composition, a mineral binder and a mineral composition which is a high temperature superconducting Bi-Sr-Ca-Cu-O material or a precursor therefore. A thick superconducting film is produced by screen printing deposition of the ink on a substrate through a mask, drying and then baking the deposited ink. The ink and film are useful in microelectronics.
