Aluminium Sulfate Including anhydrous and hydrous(18 crystal water) type. Usually, the crystal separated out from aqueous solution at the normal temperature is A12(SO4) 3.18H2O; When weathering, the average molecular structure is A12(SO4) 3.14H2O, may appear white powdery, with bright flake or crystalline flakelet, odorless, to change the taste from sweetness to slight astringency.
