Niobium foil and niobium tape applications
Pure niobium foil and strip are used in the production of synthetic diamond. Niobium foils and niobium tapes are used in luminescent materials and electric light sources. In the aerospace industry, it can also be used as an electrical vacuum device such as thermal protection, structural materials, and vacuum tubes.
