Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys.. The chemical inertness of tantalum ...

Commercially pure tantalum is deposited into and about the carbon skeleton using chemical vapor deposition/infiltration (CVD/CVI) to create a porous metal construct. Because of the crystallographic growth and orientation of the tantalum during deposition, the process results in a surface with a distinct microtexture as shown in Fig. 11.1.

As an alternative to TiO 2, Ta 2 O 5 has been successfully applied in the photodegradation of dyes [21,558–560].Ta 2 O 5 films have been fabricated on a tantalum substrate via a hydrothermal method [21].The results showed that the morphology of Ta 2 O 5 /Ta monolith, which was controlled by the crystallization temperature and duration, had great influence on the photocatalytic activity.

The Biocompatibility of Tantalum. Robert J Harling's conclusion in this article: "The information available indicates tantalum is highly resistant to chemical attack and arouses very little adverse biological response in either the reduced or oxidised forms. Many studies demonstrate excellent biocompatibility in a variety of situations ...
