99.9999%(6N)镓(真空安瓿密封)

Gallium,旧译作)是一种化学元素,它的化学符号是Ga,原子序数是31,是一种弱性金属。

在自然界中常以微量分散于铝矾土矿、闪锌矿等矿石中。

1871年,俄国化学家门捷列夫以他的元素周期律,预测「镓」的存在,称之为「eka-aluminium」,意思「铝下元素」(铝下一行的元素)。其密度、熔点等性质,与随后发现「镓」实值相差无几。

1875年,德布瓦博德兰检测在闪锌矿样品的原子光谱时发现两条紫色谱线,后来经过电解其氢氧化物的氢氧化钾溶液得到镓。德布瓦博德兰以“高卢”(Gallia)为这个元素命名,在拉丁语中这是对法国高卢的称呼。也有人认为是运用不同语言的双关语而用他的名字(其中包含“Lecoq”)命名:Le coq在法语中是“公鸡”(rooster)之意,而后者在拉丁语中又是“吊带”(gallus,与镓gallium相近)的意思。不过1877年德布瓦博德兰写文章否定这个猜测。

Gallium 镓

99.9999% (6N) gallium sealed in vacuum ampoule.

Gallium is a chemical element with symbol Ga and atomic number 31. Elemental gallium does not occur in free form in nature, but as the gallium(III) compounds that are in trace amounts in zinc ores and in bauxite. Gallium is a soft, silvery metal, and elemental gallium is a brittle solid at low temperatures, and melts at 29.76 °C (85.57 °F) (slightly above room temperature). The melting point of gallium is used as a temperature reference point. The alloy galinstan (68.5% gallium, 21.5% indium, and 10% tin) has an even lower melting point of −19 °C (−2 °F), well below the freezing point of water. Since its discovery in 1875, gallium has been used as an agent to make alloys that melt at low temperatures. It has also been useful in semiconductors, including as a dopant.
