Maps in Fes

硫化亚铁(化学式:FeS)是铁(II)的硫化物,标准状态下为黑褐色难溶于水的六方晶系晶体,具有非计量性质。它易被空气氧化,生成高价的铁氧化物(如四氧化三铁)和硫。粉末状的硫化亚铁会发生自燃。 单质铁和硫密闭高温反应,或铁(II)盐与碱金属硫化物在水溶液中作用都会生成硫化亚铁。 S8 + 8 Fe → 8 FeS Fe2+ + S2− → FeS↓ 自然界的硫化亚铁以磁黄铁矿的形式存在。它有单斜和六方两种,都为非计量化合物,缺少铁原子,化学式大约为Fe7S8。 硫化亚铁是反铁磁性的,难溶于水,但可溶于盐酸放出硫化氢气体,实验室中常作硫化氢发生剂。 FeS + 2 HCl → FeCl2 + H2S↑ 真空加热至1100 °C时,硫化亚铁开始分解。
