Aluminum Oxide(α-Alumina) nanofibers are yielded through a novel ac electrospinning process resulting in extraordinary aspect ratios, consistent purity, and consistent certification of form parameters that are difficult if not impossible to achieve using other nanofiber production methods. Aluminum Oxide nanofibers have been observed to exhibit properties including high melting temperature (≈2072°C), nanostructural stability at high temps, high surface area, electrically insulative, thermally insulative, aqueous insolubility, and low reactivity. Aluminum Oxide nanofibers have applications in absorbents and catalyst support.
