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