  • Umicore Gallium

    Gallium. The existence of gallium was predicted in 1871 by Mendeleev, who called it ekaaluminium. In 1875 Lecoq de Boisbaudran, whose curiosity had been aroused by the presence of unknown lines in the spectrum of a zinc mineral originating from the Pyrenees, succeeded in isolating the metal, which he named gallium after his native France (Gallia).
