Tantalum ribbon can take hydrogen, oxygen, and nitrogen away from the atmosphere and is the ideal product for vacuum applications in the lighting industry. Tantalum is corrosion resistant and has good thermal conductivity, it can be used in the manufacture of heating elements, vacuum tubes, and other high-temperature parts.
