arsenic

   一种化学元素。化学符号As,原子序数33,原子量74.92159,属周期系ⅤA族。古代罗马人和希腊人都把雄黄(As2S2)称为砷,中国的炼丹家则把雄黄和雌黄视为炼丹的必备药剂。1250年德意志 A.马格努斯用雄黄和肥皂共热,制得砷。砷在地壳中的含量为5×10-4%,在自然界分布很广,大多以硫化物的形式夹杂在铜 、铅、锡、镍、钴、锌、金矿中,主要砷矿有斜方砷铁矿(FeAs2)、雌黄(As2S3)、辉钴矿(CoAsS)、雄黄(As2S2)、砷黄铁矿( FeAsS)、辉砷镍矿(NiAsS)、硫砷铜矿(Cu3AsS4)等。
   砷有3种同素异形体:①灰砷 。在常温下稳定,是脆的晶体,有金属性,能传热和导电,密度5.727克/厘米3,在空气中不易被氧化。②黄砷。淡黄色晶体,由灰砷的蒸气迅速冷却后形成,密度2.026克/厘米3,在室温下暴露在空气中即被氧化为As4O6,比灰砷不稳定。③黑砷。将砷化氢加热而得,密度4.7克/厘米3,灰砷蒸气缓慢冷却也可得黑砷,它是无定形物质。砷的熔点817℃(2.8×106帕),613℃升华,在干燥的空气中稳定,在潮湿的空气中能生成黑色的氧化物薄膜,砷与水、非氧化性酸和碱不起作用,但能溶于硝酸和浓硫酸中。砷的氧化态为-3、+3、+5。砷的重要化合物有:①砷化氢(AsH3)是无色、有大蒜味的剧毒气体。②砷的氧化物有As4O6和As4O10。③砷的含氧酸有亚砷酸(HAsO2)和砷酸(H3AsO4)。砷及其化合物都有剧毒,从古至今,砒霜(氧化砷)一直被认为是能致人死命的毒药。砷的制法为先将砷的硫化物矿氧化为氧化砷,然后再用碳还原,即可得到单质砷。高纯度的砷是半导体材料硅的掺杂剂,提纯方法是先将粗砷转变为氯化砷,再通过精馏提纯,最后用氢气将三氯化砷还原为高纯砷。砷主要用作合金添加剂,用于生产印刷用合金、黄铜、耐磨合金、耐海水腐蚀钢。高纯砷用于制造半导体硅和砷化镓。三氧化二砷和砷酸盐用作杀虫剂和木材防腐剂。也用于玻璃和媒染剂生产。
