Descripción

Descripción general

Aluminum oxide (alumina, Al₂O₃), a metal oxide, is a common raw material for manufacturing ceramics. It is a good electrical insulator that shows stability at high temperature and resistance to chemicals. Alumina is an important source for aluminum and can be prepared from high-alumina ladle furnace refining slag. It can enhance the reaction rate of aldose to ketose conversion by Lobry de Bruyn–Alberda van Ekenstein transformation. It is a key constituent of NO_x storage catalysts (NSC), which are employed to get rid of nitrogen oxides from the exhaust gas of lean burn engines. Its surface passivation characteristics on crystalline silicon makes it a vaiable candidate in silicon solar cell production.

Aplicación

Aluminum oxide was used in the disposable alumina columns, to determine the adenylyl cyclase (AC) activity during the interaction of 2,3-O-(2,4,6-trinitrophenyl)-substituted nucleoside 5-triphosphates (TNP-NTPs)with VC1:IIC2 (purified catalytic subunits of membranous AC). It may be used as a dopant to produce optical fiber amplifiers and high-power fiber lasers.
