WebA shiny, silvery metal that is very resistant to corrosion. Uses One of the main uses of tantalum is in the production of electronic components. An oxide layer which forms on the surface of tantalum can act as an insulating (dielectric) layer. WebAbstract Tantalum is one of the most versatile corrosion-resistant metals known. The outstanding corrosion resistance and inertness of tantalum are attributed to a very thin, impervious, protective oxide film that forms on exposure of the metal to slightly anodic or oxidizing conditions.
WebMar 31, 2024 · Tantalum is the most corrosion-resistant metal in common use today. It is inert to practically all organic and inorganic compounds, with a corrosion resistance very similar to glass. Tantalum is often used for the manufacture of dip tubes, piping and overhead condensers.
