铍是最轻的金属之一。1879年法国化学家沃克林在分析绿柱石时发现了铍。到1928年,德国和法国的化学家分别用金属钙热还原氧化铍和用金属钾热还原氧化铍得到了少量纯度不高的金属铍。一百年后,1898年,法国化学家用纯氟化铍和氟化钾或氟化钠的熔盐电解方法,才得到了纯度为99.5～99.8％的金属铍。此后,对铍及其合金的性质、生产方法和应用进行了广泛的研究,到1925年至1932年间,德国的德古沙公司、美国的
Beryllium is one of the lightest metals. In 1879 the French chemist Walkley discovered beryllium when analyzing beryl. By 1928, chemists in Germany and France obtained a small amount of pure beryllium with low thermal purity by reducing the beryllium oxide by metallic calcium and by reducing the beryllium oxide by potassium potassium, respectively. One hundred years later, in 1898, French chemists obtained the beryllium with a purity of 99.5-99.8% by molten salt electrolysis of pure beryllium fluoride and potassium fluoride or sodium fluoride. Since then, extensive research has been conducted on the properties, production methods and applications of beryllium and its alloys. From 1925 to 1932, Germany’s Degussa Corporation,
