            WHA-108 Aluminum Oxide micro ball

            1.Chemical formula: Al2O3•nH2O n< 1
            2.Properties and uses:
                 Aluminum oxide micro ball has two crystalline phase,one type is γ-acitve aluminum oxide micro sphere,another type is γ-aluminum oxide micro sphere.
            Appearances of the two type micro sphere are all white.The γ-aluminum oxide micro sphere is alightly soluble in acid and alkali,insoluble in water.The γ-aluminum oxide micro sphere can transfer into α-aluminum oxide through calcined at 1200-1500°C.This product is widely used in decolor purification of organic liquid.
