Potassium aluminate is an inorganic compound with the formula KAlO2, which in aqueous solution exists as K[Al(OH)4]. It is used as a dyeing and printing mordant, as a paper sizing, as an accelerant in the setting of concrete[citation needed].


Potassium aluminate can be used to produce Potassium alum with Sulfuric acid in this reaction.

KAlO2 + 2 H2SO4 = KAl(SO4)2 + 2 H2O
