Iodine pentafluoride (IF5 ) - Markets & Applications

Construction materials IF5 can be used on a variety of metals to form a passive metal-fluoride film which protects the metal from further corrosion and renders it suitable for use as construction material. Booth and Pinkston *** state that metals like silver, magnesium, copper, iron and chromium are only very slightly attacked by iodine pentafluoride and that even after long periods no corrosion is visible. Arsenic, antimony and boron ignite spontaneously on contact with iodine pentafluoride, yielding iodine and the metallic fluorides. Molybdenum and tungsten react only after warming.    *** Booth, Pinkston Chemical Reviews, Vol. 41, No. 3 (1947) Preferred construction materials are monel and nickel; copper, brass and steel can also be used. Under normal conditions, highly-fluorinated polymers such as PTFE , and PCTFE, are resistant to liquid or gaseous iodine pentafluoride and are also suitable as construction materials.
