分子式:
分子量:
CAS号:

性质:周期系第V族主族(氮族)元素。原子序数33。稳定同位素:75。原子量74.92160。俗名砒。有灰、黄、黑三种同素异形体。其中灰色晶体具有金属性,但脆而硬。密度5.72。在615℃升华。熔点817℃(在约3.6兆帕即36大气压下)。化合价±3和±5。与水、碱或非氧化性酸不起反应。溶于硝酸、浓硫酸和王水。在空气中其表面很快生成氧化物而失去光泽。在200℃时通入氧即发荧光。砷和砷的可溶性化合物皆剧毒!用于制砷酸盐、硬质合金(与酮、铅等)、药物、防腐剂、媒染剂、杀虫药等。高纯砷用于半导体和激光技术。自然界中主要以化合物形态存在,间或成单质存在。在砷硫铁矿FeAsS、雄黄As4 S4 、雌黄As2 S3 等。可由三氧化二砷用碳还原而制得。
