Category: Tantalum

Tantalum is a ductile metal. Tantalum has excellent corrosion resistance to most chemicals except hydrofluoric acid. Tantalum metal has a melting point exceeded only by tungsten & rhenium. The melting point of tantalum is approximately 3017 degrees Celsius. Tantalum’s main end uses are in capacitors, vacuum furnaces, chemical process equipment, nuclear reactors, and aircraft parts.

Why Tantalum Is Important?

0 Comment

Why Tantalum Is Important? Tantalum occurs in columbium ores. As the demand for columbium increases, increasing amounts of tantalum concentrates become available. After a difficult and complex separation and reduction process, both metals are obtained in the form of powder. The powder is pressed in dies to form bars which are vacuum sintered by passing […]
