Alumina, also known as activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square meters/g. The compound is used as a (to keep things dry by absorbing water...
High purity aluminum oxide
is the raw material for sapphire crystal. This type of pressed pellets are made from ultra high purity alumina. It is designed to provide high filling in crucibles used to make sapphire single crystals. The alumina materials RBST supplied are produced with latest eco-friendly and high technology. As a supplier for advanced materials, we continuously improving the service by cooperate with the manufacturers with high efficiency large volume production.
High purity alumina powder is a compound, commonly known as aluminum oxide (Al2O3). It is odorless, white, crystalline powder. It has very high melting point. It is insoluble in water and difficult solubility in mineral acids and strong alkali. The variety formed at very high temperature is quite inert chemically. It is amphoteric in nature, and is used in various chemical, industrial and commercial applications.
