  This study proposes a novel solution blow spinning technique (SBS) for
fabricating YBCO ceramic nanofibers. The precursor solutions were obtained from
Y, Ba, and Cu metallic acetates (Ac) and poly(vinyl pyrrolidone) (PVP, Mw =
360,000). Ac:PVP concentrations of 1:1 and 5:1 were tested, resulting in
ceramic nanofibers with average diameters of 359 and 375 nm, respectively.
X-ray diffraction confirmed the formation of a pure phase of YBa2Cu3O7-x. This
is the first study to use SBS for fabricating YBCO nanofibers, and this
technique shows promise for obtaining high-quality ceramic materials.
