The use of tantalum in the process industry | SpringerLink

Tantalum is one of the refractory metals, so named because of their excellent high-temperature properties. 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,
