Tantalum usage has developed significantly over recent years and is now used extensively in the manufacture of capacitors in electronic applications such as mobile phones and computers; in super alloys with nickel and cobalt for the aerospace industry; in specialty metal products for the medical, pharmaceutical, and chemical industries; and in metal carbide for the metal working tools industry.
Tantalum is also famous for its resistance to corrosion by acids; in fact, below 150°C, Tantalum is almost completely immune to corrosion by aqua regia. Due to its resistance to attack by body fluids, Tantalum provides an excellent material for medical devices. Tantalum has good thermal conductivity, and is used is in the manufacture of heating elements, vacuum tubes and other high ...
Tantalum is a metallic element with a bluish tint and excellent ductility. Tantalum is the third most refractory metal, only after tungsten and rhenium, with a melting point of 2980 ℃, element symbol Ta, atomic number 73, and a density of / cm³. Except for the basics above, what else should we know about tantalum?

Refractory Metal Coatings Freestanding Structures. Through chemical vapor deposition, Ultramet fabricates refractory metal coatings and freestanding structures of tungsten, rhenium, tantalum, molybdenum, and niobium.
Like Niobium, Tantalum is a heattolerant refractory metal with excellent corrosion resistance. Often alloyed with other metals, tantalum is used to make super alloys used in chemical processing, jet engines and nuclear reactors. Its oxidation properties also make it an excellent choice for many electronic applications, including electrolytic capacitors and highpower resistors. Tantalum is ...
The refractory metals include niobium (also known as columbium), tantalum, molybdenum, tungsten, and rhenium. With the exception of two of the platinumgroup metals, osmium and iridium, they have the highest melting temperatures and lowest vapor pressures of all metals. The refractory metals are readily degraded by oxidizing environments at moderately low temperatures, a property that ...
There is no metal entirely immune from recession but the ones that might hold up better than most, I would suggest, are Tantalum, Zirconium, Hafnium and Rhenium. Each of these metals share a common thread in that they are dominated by companies who hold a significant market share of a small market, and serve industries
Tungsten and Rhenium are both refractory metals. By fusion of the two components, with the effect of Rhenium, TungstenRhenium alloy gets better ductility, higher recrystallization temperature, better creep resistance and higher resistivity than pure Tungsten. TungstenRhenium alloy has good mechanical properties and can be machined and welded.
Tantalum. Download Datenblatt. Lieferprogramm (PDF) Das Element Tantal wurde von Andres Gustav Ekeberg im Jre 1802 in Finnland entdeckt. Zu den wichtigsten Förderländern zählen heute Australien, Brasilien und Kanada. Die weltweite Jresproduktionsmenge beträgt ca. 1400 t. Wichtigste Eigenschaften. außergewöhnlich hohe Korrosionsbeständigkeit, speziell in diversen Säuren wie ...
Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silverygray, heavy, thirdrow transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth''s crust.

· Tantalum is used in many industries, and it is deemed a critical component in many items. But the main and most important function of the metal is in the manufacture of electrolytic capacitors for the electronics industry. These types of capacitors make use of the metal''s tendency to form a protective oxide surface layer. This results in high capacitance in a very small volume, which give ...
Tantal ist ein unedles Metall und reagiert bei hohen Temperaturen mit den meisten Nichtmetallen, wie Sauerstoff, den Halogenen oder Kohlenstoff. Bei Raumtemperatur ist das Metall allerdings durch eine dünne Schicht aus Tantal (V)oxid geschützt und damit passiviert. Eine Reaktion findet erst ab einer Temperatur von etwa 300 °C statt.
· I have never machined Tantalum or Rhenium, but I did a turning job in TZM 364 which is a sintered alloy containing % molybdenum alloyed with Titanium and Zirconium. That shit was nasty. It did chip just like cast iron and made the same kind of noise you get when turning cast iron, but nastier grinding, rumbling.
Rhenium is one of the refractory metals, but differs considerably in that it''s crystal structure is a closepacked hexagonal pattern, as opposed to bodycentered cubic, such as in niobium, tantalum, molybdenum and tungsten.

In its pure state, tantalum is a greyblue metal, which can be polished to a silvery sheen. You can hammer it into sheets, and draw it into wires. And, as Ekeberg discovered, it''s tough stuff. Tantalum alloys turn up in hot places such as jet engines and nuclear reactors because the metal''s melting point is around 3,000 degrees centigrade among the metals, only tungsten and rhenium are ...
