Merck, A1522-1KG, Aluminum oxide

General description
We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Aluminum oxide serves as a multifunctional additive or coating in lithium-ion batteries, helping stabilize electrode–electrolyte interfaces, suppress side reactions, improve thermal stability, and extend cycle life. By enabling safer, longer-lasting cells, it reduces material waste and energy use across the battery lifecycle. Click here for more information.
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 NOx 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.
Application
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.
