中文百科

氧化的钡

(Barium)是化学元素周期表中的元素,它的原子序数是56,化学符号是Ba。它是周期表中2A族的第五个元素,是一种柔软的有银白色金属光泽的碱土金属。由于它的化学性质十分活泼,从来没有在自然界中发现钡单质。

钡在自然界中最常见的矿物是重晶石(硫酸钡,BaSO4)和毒重石(碳酸钡,BaCO3),二者皆不容于水。钡的名称源于希腊文单词βαρύς (barys),意为“重的”。 它在1774年被确认为一个新元素,但直到1808年电解法发明不久后才被归纳为金属元素。

钡在工业上只有少量应用。过去曾用它作为真空管中的吸气剂。它是YBCO(一种高温超导体)和电瓷的成分之一,也可以被添加进钢中来减少金属构成中碳颗粒的数量。钡的化合物用于制造烟火中的绿色。硫酸钡作为一种不溶的重添加剂被加进钻井液中,而在医学上则作为一种X光造影剂。可溶性钡盐因为会电离出钡离子所以有毒,因此也被用做老鼠药。

Barium 钡

Oxidized barium
Sir Humphry Davy, who first isolated barium metal
Barite, left to right: appearance, graph showing trends in production over time, and the map showing shares of the most important producer countries in 2010.

Barium is a chemical element with symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal. Because of its high chemical reactivity barium is never found in nature as a free element. Its hydroxide was known in pre-modern history as baryta; this substance does not occur as a mineral, but can be prepared by heating barium carbonate.
