Abstract

Boron, a black metallic appearing element, was prepared by Gay-Ltjssac and Thenaed as far back as 18081. However, its best known derivative, borax, was known to the Arabs as Tinkal and was used in melting processes in the sixteenth century. Boric acid was prepared by Hombebg2 in 1702 and found wide application as “sal Sedativum”. Also in 1808, Davy3 obtained amorphous boron by the electrolysis of boric acid and a crystalline modification was described by Wöhler and Sainte-Claxre Develle in 18564. Large deposits of boron minerals are found in various parts of the world. The most important stocks are located in Tuscany (Italy), in the southwestern part of the United States, and in Northern Chile and neighboring parts of Argentina, Peru and Bolivia. Smaller deposits of commercial interest are found in Turkey, Central Asia (Tibet) and near Stassfurt, Germany. The percentage of boron in the earth’s crust is estimated at about 0.001%.
