Aluminum Oxide (CAS: 1344-28-1), high purity alumina series is mainly used for high-pressure sodium lamps, new luminescent materials, special ceramics, advanced coatings, tricolor, catalysts and some high-performance materials. There are different crystal forms, mainly α and γ two variants. Aluminum hydroxide can be heated and dehydrated to obtain alumina. The alpha type alumina that exists in nature is called corundum. Its hardness is second only to diamond. A small amount of impurities can make corundum have various colors and lustre, which is called gemstone. Aluminum Oxide application: Luminescent material: It is used as the main raw material of rare earth trichromatic phosphor, long afterglow phosphor, PDP phosphor and led phosphor. Transparent ceramics:In traditional glazes, alumina is often used for whitening. Single crystal:Used for making ruby, sapphire and yttrium aluminum garnet. High strength high alumina ceramics. Abrasive materials:Abrasive for manufacturing glass, metal, semiconductor and plastic. Diaphragm:Used for manufacturing lithium battery diaphragm coating. Others:Used as active coating, adsorbent, catalyst and catalyst carrier, vacuum coating, special glass raw materials, composites, resin filler, bioceramics and so on. As adsorbent, desiccant, abrasive,thickening and anti-caking agent; As filler for paints and varnishes; In manufacture of alloys,refractories, ceramic materials, electrical insulators and resistors, dental cements, glass, steel, artificial gems; in coatings for metals, etc.; As catalyst for organic reactions. As an insoluble carrier for mineral pigment, and is frequently mixed into mineral powder makeup. Because of its abrasive texture, many use these crystals to exfoliate and resurface the skin-particularly with Microdermabrasion. As a chromotagraphic matrix; originally called Brockmann aluminum oxide when used for this purpose. The minerals corundum (hardness = 9) and Alundum (obtained by fusing bauxite in an electric furnace) are used as abrasives and polishes; In manufacture of cosmetic products like blush, powder foundation, lipstick and facial cleanser.
