Abstract (en)
[origin: WO9400385A1] High temperature superconductors (e.g. Y-Ba-Cu-O) can be formed at commercial quantities with high phase purities by conducting the coprecipitation process at a constant pH. By selecting a precipitate (e.g. oxalates) which confers plastic properties to the precipitated product, a variety of shaped HTSC compounds can be made.
