Growth of alumina microcones by high-temperature oxidization
Source abstract
Abstract
An alumina microcone, a novel crystallized form of alumina, has been grown by heating high-purity metallic aluminum foil in air at a temperature above 1273 K. The microcone was characterized by X-ray diffraction (XRD), scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX) and focused ion beam (FIB) technology. The results of XRD and EDX indicate that the composition of the microcone is alumina. The microcone is hollow and has a layered structure identified by FIB cutting and milling. The cone is made of many nanocones. The microcone is grown from one growth nucleus layer by layer along the cone axis, and its growth direction is from bottom to top.
