Potassium alum dodecahydrate occurs in nature as a sulfate mineral called alum-(K), typically as encrustations on rocks in areas of weathering and oxidation of sulfide minerals and potassium-bearing minerals. In the past, potassium alum has been obtained from alunite (KAl(SO 4) 2·2Al(OH) 3), mined from sulfur-containing volcanic sediments. Alunite is an associate and likely potassium and aluminiu… Webb20 jan. 2024 · The experimental results show that the optimal parameters for KAl(SO4)2 sealing are 35 °C, with the pH value of 8, the concentration of 8 g/L, and the sealing time of 3 min. The corrosion resistance of the KAl(SO4)2 sealed sample can be significantly improved than that of unsealed one, and is obviously superior to that of the conventional …
