分子式AlH24KO20S2

分子量474.4

熔点92.5 °C

应用领域Uses: Occurs naturally as efflorescence on alum shale and as feather alum on lava、Used to dress fur skins (one of oldest methods)、Forms aluminum potassium sulfate (CAS 10043-67-1) when heated above melting point (92.5 deg C)、[Ullmann] The most important alums are aluminum potassium sulfate、aluminum ammonium sulfate、and aluminum sodium sulfate. Aluminum potassium sulfate (hydrated) has the formula KAl(SO4)212H2O. Aluminum sulfate is used as a replacement of the alums. Hydrolysis of the alums yields aluminum hydroxide as a precipitant. Industrial uses include paper sizing、water purification、and textile dyeing (mordant). Alums are also used in pickling、baking powder、fire extinguishers、and astringents.
