Aluminum oxide, is useful to produce aluminum metal. It has many uses in pharmaceutical and industrial manufacturing processes as an adsorbent, desiccating agent, and catalyst, and in the manufacture of dental cements, available in toothpaste, as a dispersing agent food additive, and for uses in hemodialysis. Tailored aluminum oxide layers plays an important role for the bipolar current adjustment in the plasma electrolytic oxidation process. Red phosphorus/aluminum oxide composites play an essential role as flame retardants in recycled poly(ethylene terephthalate).
