|Section2= |Section3= |Section4= |Section7= }} Aluminium carbide, chemical formula Al4C3, is a carbide of aluminium. It has the appearance of pale yellow to brown crystals. It is stable up to 1400 °C. It decomposes in water with the production of methane. ==Structure== Aluminium carbide has an unusual crystal structure that consists of two types of layers. It is based on AlC4 tetrahedra of two types and thus two types of carbon atoms. One is surrounded by a deformed octahedron of 6 Al atoms at a distance of 217 pm. The other is surrounded by 4 Al atoms at 190–194 pm and a fifth Al atom at 221 pm.〔 Other carbides (IUPAC nomenclature: methides) also exhibit complex structures. 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 carbide」の詳細全文を読む スポンサード リンク
