|Section2= |Section3= }} 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.〔Anthony John Downs, (1993), ''Chemistry of Aluminium, Gallium, Indium, and Thallium'', Springer, ISBN 978-0-7514-0103-5〕 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.〔http://books.google.co.uk/books?id=IDsXBQAAQBAJ&pg=PA311&lpg=PA311&dq=existence+of+aluminium+carbonate&source=bl&ots=M4Bniin9rM&sig=F_kHdV_Itn9a-Xgz3cg1Pej145k&hl=en&sa=X&ei=6xFyVMiKAZPSaKHbgjg&ved=0CCkQ6AEwATgK#v=onepage&q=existence%20of%20aluminium%20carbonate&f=false〕 The reaction of aluminium sulfate and sodium bicarbonate forms carbon dioxide and aluminum hydroxide which stabilises the formation of a foam.〔 This reaction was the basis of an early fire extinguisher invented by Aleksandr Loran in 1904. * Dawsonite 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Aluminium carbonate」の詳細全文を読む スポンサード リンク
