|Section2= |Section3= |Section7= }} Beryllium nitride, Be3N2, is a nitride of beryllium. It can be prepared from the elements at high temperature (1100–1500 °C),〔Egon Wiberg, Arnold Frederick Holleman (2001) ''Inorganic Chemistry'', Elsevier ISBN 0-12-352651-5〕 unlike Beryllium azide or BeN6, it decomposes in vacuum into beryllium and nitrogen.〔 It is readily hydrolysed forming beryllium hydroxide and ammonia.〔 It has two polymorphic forms cubic α-Be3N2 with a defect anti-fluorite structure, and hexagonal β-Be3N2.〔 It reacts with silicon nitride, Si3N4 in a stream of ammonia at 1800–1900°C to form BeSiN2.〔 ==Preparation== Beryllium nitride is prepared by heating beryllium metal powder with dry nitrogen in an oxygen-free atmosphere in temperatures between 700 and 1400 °C. 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「Beryllium nitride」の詳細全文を読む スポンサード リンク
