Abstract
321,391. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). July 27, 1928. Filaments.-Tungsten or other metal is coated with vanadium by heating to incandescence in an atmosphere of vanadium iodide so that vanadium is precipitated thereon. If the atmosphere is substantially free from impurities such as silicon, the vanadium produced is ductile. The tungsten &c. wire is suspended by leading-in wires from the neck of a sealed quartz vessel which is provided with a tube connected to a pump which removes air and any harmful gases produced during the reaction. Vanadium iodide or vanadium and iodine is then introduced in the vessel, which is heated to 800‹-1000‹ C., and the vanadium iodide, which is present or is produced, is dissociated, the vanadium settling on the wire. In a modification, a core-body is heated in an atmosphere of vanadium iodide and the vanadium-coated body is introduced into the reaction body with iodine. On heating the vessel, vanadium iodide is produced, and on further heating, dissociated, the vanadium being precipitated on a second core.
