General description

Aluminum oxide (alumina) is a common raw material for ceramic materials. It is a good electrical insulator that shows stability at high temperature and resistance to chemicals. Alumina is an important source for aluminum and has been prepared from high-alumina ladle furnace refining slag. It is reported to enhance the reaction rate of aldose to ketose conversion by Lobry de Bruyn–Alberda van Ekenstein transformation. It is a key constituent of NOx storage catalysts (NSC) which is employed to get rid of nitrogen oxides from the exhaust gas of lean burn engines. A study of the surface passivation characteristics of aluminium oxide on crystalline silicon shows many advantages which can be applied in silicon solar cell production.

Application

Aluminum oxide may be used as a dopant to produce optical fiber amplifiers and high-power fiber lasers.
