Description



Product Description




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.
Our company product mainly is 4N and 5N. It is the pre-cursor material for the manufacture of sapphire glass and ceramic coated Lithium-Ion-Battery (Li-B) separators.
