“…Nowadays, aluminum oxide, commonly referred to as alumina, is a key component of various products, devices, and equipment. For instance, alumina is extensively employed as a dielectric material in capacitors and other electrical devices, as substrate and furnace materials, filler in cosmetic formulations, hard coatings and soft abrasives, and as support for catalysis . The widespread use of alumina is intimately linked to the functional properties of its various crystallographic polymorphs (corundum, sapphire, gamma alumina, etc.)…”
