| CAS Number | 7784-24-9 |
|---|---|
| Molecular Formula | AlH24KO20S2 |
| Molecular Weight | 473.98 g/mol |
| Melting Point | 92.5 °C |
| Applications | 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.
