An aluminate is a compound containing aluminium and oxygen. When precipitated from solution, the anion condenses with more electropositive elements. The generally accepted form of the aluminate is a mononuclear tetrahedral complex that is negatively charged, Al(OH)4− or AlO2−. Examples of aluminate compounds include sodium aluminate (Na2Al2O4) and potassium aluminate (K2Al2O4), both being alkali-ion precipitates of the tetrahedral monomer obtained from an alkaline solution. Aluminate can also refer to the polyatomic ion AlO3−
