|Section2= |Section3= }} Americium dioxide (AmO2) is a black compound of americium. In the solid state AmO2 adopts the fluorite, CaF2 structure.〔 〕 It is used as a source of alpha particles. ==Historical Use== Synthesis of americium dioxide involves precipitating a solution of americium in hydrochloric acid (HCl) solution as described by the Oak Ridge National Laboratory The demand for americium dioxide stems from the difficulty of storing the element americium as a liquid in the hydrochloric acid solution because the alpha radiation and hydrochloric acid decomposes storage containers over time. To solve the liquid storage problem, Oak Ridge National Laboratory devised a synthesis to turn liquid americium Hydrochloric acid solution into a precipitated form of americium for safer handling and more efficient storage.〔 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「Americium dioxide」の詳細全文を読む スポンサード リンク
