This colorless solid can be prepared synthetically but also occurs in nature. ==Production and occurrence== The majority of aluminium fluoride is produced by treating alumina with hexafluorosilicic acid: :H2SiF6 + Al2O3 → 2 AlF3 + SiO2 + H2O Alternatively, it is manufactured by thermal decomposition of ammonium hexafluoroaluminate.〔J. Aigueperse, P. Mollard, D. Devilliers, M. Chemla, R. Faron, R. Romano, J. P. Cuer, "Fluorine Compounds, Inorganic" in Ullmann’s Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2005.〕 For small scale laboratory preparations, AlF3 can also be prepared by treating aluminium hydroxide or aluminium metal with HF. Aluminium fluoride trihydrate is found in nature as the rare mineral rosenbergite. 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 fluoride」の詳細全文を読む スポンサード リンク
