tantalum processing and fabrication

The use of tantalum in the process industry

Tantalum is one of the refractory metals so named because of their excellent high-temperature properti These metals especially tantalum have remarkable corrosion-resisting properties due to an inherent self-healing oxide layer that protects the tantalum against the most hostile environments except those containing fluorine or fluorides In this article the production fabrication...
