Product Detail
Tantalum has good thermal conductivity, and is used is in the manufacture of heating elements, vacuum tubes and other high temperature parts.
Another major use of tantalum is for electronic components, and due to its absorption properties, tantalum is an excellent getter of residual gasses in evacuation tubes. Tantalum films provide very high capacitance per volume allowing miniaturization of electronics and circuitry. Tantalum capacitors are use in computers and cellular phones.
Tantalum is also famous for its resistance to corrosion by acids; in fact, below 150?C, Tantalum is almost completely immune to corrosion by aqua regia. Due to its resistance to attack by body fluids, Tantalum provides an excellent material for medical devices.
