abstract = "Progress in key areas is reported for the continued development of the silver-addition process for preparing textured `1223' Tl-Ca-Ba-Cu-oxide thick films; film homogeneity, film growth mechanism, scale-up, and flexible substrates. As a consequence of refinements in the precursor oxide film preparation and the development of a `flow' reactor, superconducting films on polycrystalline YSZ have been prepared that exhibit zero-field Jc values (77 K) as high as 366,000 A/cm2. Advantage has been taken of these process improvements to prepare a textured `1223' thick film with T c = 109 K on a zirconia coated metal substrate. When placed in a magnetic field there is an initial drop in Jc, attributed to the presence of weak links. However, after this initial drop, the film exhibits the characteristic behavior expected of strongly linked `1223'. The film growth mechanism underlying the silver-addition process is discussed in light of the results of microstructural studies of samples quenched at different times into the thallination process.",
