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 makes it a valuable substance for laboratory equipment and a substitute for platinum.
Tantalum sputtering target is used in integrated circuits and Thin Film Transistor Liquid Crystal Display (TFT-LCD). SAM specializes in producing high purity Aluminum Sputtering Targets with the highest possible density and smallest possible average grain sizes.

Capacitors
About half the tantalum consumed each year is used within the electronics industry, mainly as powder and wire for capacitors. The tantalum capacitor is favored in space-sensitive, high-end applications in telecommunications, data storage and implantable medical devices.
Semiconductors
Using the physical vapor deposition (PVD) process, tantalum is “sputtered” onto semiconductor substrates to form a thin film diffusion barrier to protect the copper interconnects. Tantalum sputtering targets are used in a variety of other products, including magnetic storage media, inkjet printer heads and flat panel displays.
Engine turbine blades
The metal’s high melting point and resistance to corrosion makes it suitable for alloying applications. Tantalum is used in nickel based superalloys where the principal applications are turbine blades for aircraft engines and land based gas turbines.
Chemical processing equipment
Tantalum’s high resistance to corrosion and high temperature makes the metal an ideal material of construction for liners in vessels, piping, valves and heat exchangers in the chemical and pharmaceutical industries.

As advertised in the picture. Looks a little smalled than the picture, but is a bar of tantalum which is what I need and I don't care how it looks, so perfectly satisfied and price seemed good.
