This product has white sand shape, and the properties of high chemical purity, stronge ability of impurity adsorption, and good decoloration effect. It is a kind of alumina with specific structure, and non-toxic, odorless, tasteless, insoluble in water and organic solvents, but soluble in strong acid and alkali solution in high temperature.

It can be used as special adsorbent for LCD production in electronics industry. Under the same test conditions with imported products, the product has the same performance in indicators of impurities adsorption effect, lifetime, through rate, etc. And some of indicators are superior to the imported products.
