Tantalum ingot is an associated metal of tantalum ,characterized in high strength ,high conductivity ,resistance to corrosion by liquid base metals ,section with low neutron capture ,etc ,widely used for steel ,ceramics ,electronics ,nuclear energy industries and superconductor technology.
Used: Tantalum is used for making electronic capacitors and vacuum furnace parts. The metal is widely used in fabricating chemical process equipment, nuclear reactors, heat exchangers, aircraft and missile parts. Tantalum is entirely immune to body liquids and is a nonirritating metal. It has, therefore, found wide use in making surgical appliances. Tantalum oxide is used to make special glass with a high index of refraction for camera lenses.
