Product introduction
Spherical porous, non-toxic, tasteless and odorless, in white powder form. Insoluble in water and ethanol, it can be dissolved in acid or alkali solution, and can react with water to produce aluminum hydroxide gel with high strength. Activated alumina is an important branch of non-metallurgical grade alumina industry, it refers to γ, κ, θ, η, δ, χ and other transition phase alumina and alumina compounds containing some water (molecular formula Al2O3-nH2O, 0≦n﹤1)
