补充资料:氦
氦 helium 一种化学元素 ,化学符号He ,原子序数 2 ,原子量4.002602,属周期系零族,为稀有气体的成员之一。元素的英文名称来源于希腊文h ![]()
氦是无色、无臭、无味的气体,熔点-272.2℃(2.5×106帕),沸点-268.9℃,气体密度0.1785克/升(0℃,1×105),帕界温度-267.8℃,临界压力2.26×105帕,在水中的溶解度8.61厘米3/千克水。氦有两种液相:He(I)为高温液相,是一种普通液体,当温度下降至2.18K时,He(I)变为He(Ⅱ),后者是一种超流体,具有气体性质。氦主要从天然气中获得或从以天然气为原料的工业生产中得到,例如以天然气为原料合成氨时,,可从尾气中回收氦。氦用于充填高空气球和飞艇,不会发生燃烧或爆炸。在焊接和熔炼稀有金属时用作保护气体。按一定比例配成的氦-氧混合气是供潜水员呼吸用的气体。还可做温度低于14K的超低温制冷剂和气相色谱法中用的载气。 |
