一、歷史概論沃克林於1791年在鑛物綠柱石中發現了今日称為鈹的元素。製取純鈹是非常困难的,僅在1827年才用金屬鈣还原鈹氧化物的方法成功地製取了不完全純的鈹。製取鈹困难的原因是由於一直到二十世纪己開始,鈹僅具有科学的意義,实際的应用尚未發現。在二十世紀二十年代末,卽在第一次析出金屬鈹的試驗後100年,在工業上才首次嘗試了有電解熔融鹽類的方法製取铍。目前,如众所知,鈹具有許多有很大意義的性質,因此 I. Introduction to History Walkerling discovered elements called beryllium today in mineral beryl in 1791. Preparation of pure beryllium is very difficult, and only in 1827 with calcium metal reduction of beryllium oxide successfully prepared incomplete pure beryllium. The reason why beryllium is difficult to obtain is because beryllium has only scientific significance since the beginning of the twentieth century. The actual application has not been found yet. In the late 1920s, it was the first time in the industry 100 years after the first test of metal beryllium deposition that beryllium had been tried for the electrolysis of molten salts. At present, as is well known, beryllium has many properties of great significance
