Use

Tantalum was first used in the manufacture of filament for electric lamps at the turn of the 20th century. Today, tantalum is in high demand due to the development of radio, radar and x-ray technology. Tantalum's affinity for absorbing gases helps maintain a deep vacuum. Its emissivity, as well as its ability to adsorb gases and refractoriness, determine its application for the production of parts of electric-vacuum devices.
