Virtually all the aluminium hydroxide used commercially is manufactured by the Bayer process [10] which involves dissolving bauxite in sodium hydroxide at temperatures up to 270 °C (518 °F). The waste solid, bauxite tailings , is removed and aluminium hydroxide is precipitated from the remaining solution of sodium aluminate .
All three are prepared by direct reaction of their elements at about 1,000 °C (1,832 °F) and quickly hydrolyse completely in water to yield aluminium hydroxide and the respective hydrogen chalcogenide. As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having ...
Aluminium carbonate (Al 2 (CO 3) 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 (NaAlCO 3 (OH) 2) and hydrated basic aluminium carbonate minerals scarbroite (Al 5 (CO 3)(OH) 13 •5(H 2 O)) and ...
