TaTantalum
180.94788
DESCRIPTIONTantalum is a blue-gray, transition metal that is fabricated by the process of hydrometallurgy. Part of the refractory metals group, tantalum is very hard, extremely ductile in the annealed condition, highly conductive of heat and electricity and has the fourth highest melting point (3017°C) of any metallic element. Tantalum is best noted for its chemical inertness and high resistance to corrosion by acids. In fact, below 150°C it is almost completely immune to corrosion by aqua regia. Tantalum has proven to be a cost-effective solution for dental and medical devices due to resistance to attack by body fluids.
APPLICATIONSElectronic Industry: Capacitors, cathodes for use in electrochemical analysis, computer components, camerasMedical Industry: Surgical implants, hypodermic needles, surgical tools Dental Industry: Dental instruments and dental spatulas
