Tantalum Metal/ Sputtering Target

Tantalum Metal/ Sputtering Target

CAS #: 7440-25-7
Linear Formula: Ta
EC No.: 231-135-5

Tantalum Metal is a silver-gray active metal with a molecular formula of Ta. It has excellent chemical properties and is extremely resistant to corrosion. It does not react with hydrochloric acid, concentrated nitric acid and sulfuric acid under both cold and hot conditions. It can be used to manufacture evaporation vessels, etc. It can also be used as an electrode, rectifier, and electrolytic capacitor of an electron tube. Medically used to make thin slices or thin lines, and to repair the damaged tissue. Although Tantalum is highly resistant to corrosion, its corrosion resistance is due to the formation of a stable tantalum pentoxide (Ta2O5) protective film on the surface.

Application

It is mainly used in the manufacture of electrode, rectifier, and electrolytic capacitor of an electron tube. Medically used to make thin slices or thin lines, and to repair the damaged tissue. Although Tantalum is highly resistant to corrosion, its corrosion resistance is due to the formation of a stable tantalum pentoxide (Ta2O5) protective film on the surface.
