99.999% Pure Tantalum

Tantalum is a shiny gray, very hard and yet ductile heavy metal from the vanadium group, it is easy to deform and weld. Tantalum is one of the refractory metals, is very resistant to almost all acids (except hydrofluoric acid) and has a high absorption capacity for hydrogen and nitrogen. In nature, tantalum occurs only in combination with niobium.

Tantalum is used in electrical engineering, chemistry, in high-temperature furnace construction, in evaporation systems and even in nuclear technology. Rust and acid-resistant steels are added to tantalum as an alloy component. Tantalum carbide is used to manufacture hard metal.
Tantalum is considered a rare element on earth, the continental crust has a content of 2 ppm, the earth's shell 8 ppm. In the solar system, tantalum is even the stable element that is the least common.

Nevertheless, tantalum is used in many areas. More than half of the tantalum extracted worldwide is used to build very small, high-capacity capacitors. These are mainly used in the manufacture of cell phones and in automobile construction. Tantalum can also be used for medical implants because it is non-toxic.

With a melting point of almost 3,000 ° C and its exceptional resistance to corrosion, tantalum is also used in numerous industrial areas.

Tantalum alloys ensure durability
Due to its stable properties, tantalum is used in some refinements. In the chemical industry, alloys made of tantalum and tungsten can not only line reaction vessels, but also heat exchangers and pumps. Even the so-called superalloys that are used in the construction of aircraft turbines often contain up to 9% tantalum.

Tantalum generally provides increased strength and resistance of the material through its addition.
