Abstract

Al2O3 nanofibers were produced with the electrospinning technique based on a precursor solution of PVP with aluminum 2,4-pentanedionate. After fiber deposition onto ceramic specimens, specimens were calcinated at a maximum temperature of 1400 °C, similar to the manufacturing temperature of commercially available whitewares. Structural and morphological characterization of the produced alumina nanofibers was performed as well as a vast mechanical characterization of ceramic glazed specimens with incorporated nanofibers. Without any significant alteration in the aesthetics properties of the glaze, a 10-% increase in the maximum allowable loads before break was noted.
