In this study, boron-doped poly(vinyl) alcohol/HfO 2 nanofibers were prepared by electrospinning using PVA as a precursor. The effect of boron doping was investigated in terms of solution properties, morphological changes and thermal characteristics. Nanofiber mats were calcined first at 800°C. Then, the calcined products were pelleted and sintered at a rate of 8°C/min and remained 2 h at 850°C at atmospheric conditions to produce ultrafine ceramic nanocrystalline powders. The fibers and nanocrystalline powders were characterized by FT-IR, XPS, XRD and SEM. The addition of boron did not only increase the thermal stability of the fibers, but also their diameters, which yielded stronger fibers.
