Aluminium carbonate (Al2(CO3)3), is a carbonate of aluminium. It is not well characterized; one authority says that simple carbonates of aluminium, gallium and indium are not known.[1] Basic aluminium carbonate, the mineral dawsonite, is a known compound.
Preparation
There is no evidence that aluminium carbonate is formed in double decomposition reactions, soluble carbonates are sufficiently alkaline to precipitate aluminium hydroxide and produce carbon dioxide.[2] The reaction of aluminium sulfate and sodium bicarbonate forms carbon dioxide and aluminum hydroxide which stabilises the formation of a foam.[2] This reaction was the basis of an early fire extinguisher invented by Aleksandr Loran in 1904.
