Aluminium carbonate (Al₂(CO₃)₃), is a carbonate of aluminium. It is not well characterized; one authority says that simple carbonates of aluminium are not known.^[2] However related compounds are known, such as the basic sodium aluminium carbonate mineral dawsonite (NaAlCO₃(OH)₂) and hydrated basic aluminium carbonate minerals scarbroite (Al₅(CO₃)(OH)₁₃•5(H₂O)) and hydroscarbroite (Al₁₄(CO₃)₃(OH)₃₆•nH₂O).^[3]^[4]^[5]
