General description

The structure of tantalum is body centered cubic (BCC) metal. It is a refractory metal; stable up to very high temperatures. Tantalum is ductile at room temperature and moderately ductile at cryogenic temperatures. Compton profile of highly pure thin elemental foil of tantalum was investigated using IGP type coaxial photon detector.1
We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives. This is an enabling product and can be used as a precursor for thin layer deposition, which is an efficient technique for finding high-performance materials. Click here for more information.

Application

0.05mm thick tantalum foil was filled with 12C or 13C powder to act as carbon source emitting low energy carbon atoms.
