What are the properties of tantalum?

Tantalum is dark (blue-gray), dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The metal is renowned for its resistance to corrosion by acids; in fact, at temperatures below 150 °C tantalum is almost completely immune to attack by the normally aggressive aqua regia.

What is tantalite ore?

Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.

What makes tantalum unique?

Tantalum has several unique characteristics that have led to its increased use in the 21st century. It is a highly stable metal that is almost immune to chemical degradation at temperatures lower than 302 °F (159 °C). It has a melting point of 5,463 °F (2,996 °C), the fourth highest of all metals.

What is tantalite stone?

Tantalite 1 It is a stone that helps to ease away such thought that contains poor or wrongful judgement as well as thought that contains different types of negativity. This stone teaches the being to not go to deep into the waters to soon.

What is the difference between tantalum and tantalite?

As nouns the difference between tantalite and tantalum is that tantalite is (mineralogy) a dark-brown mineral that is an ore of tantalum and niobium, of the chemical formula (fe]], mn) ta2[[oxygen|o6 while tantalum is a metallic chemical element (symbol ta) with an atomic number of 73.

What are 3 uses of tantalum?

Uses of tantalum More than half of tantalum’s use is for electrolytic capacitors and vacuum furnace parts. The element is also used to make chemical process equipment, nuclear reactors, aircraft and missile parts. Tantalum has found use in making surgical appliances because it’s completely immune to body liquids.

Is tantalum hard or soft?

Tantalum is a silvery metal that is soft in its pure form. It is a strong and ductile metal and at temperatures below 150°C (302°F), this metal is quite immune to chemical attack. It is known to be resistant to corrosion as it displays an oxide film on its surface.

What is tantalum mostly used for?

Tantalum is used in a variety of alloys to add high strength, ductility and a high melting point. When drawn into a fine wire, it’s used as a filament for evaporating metals such as aluminum. More than half of tantalum’s use is for electrolytic capacitors and vacuum furnace parts.

What element family is tantalum?

Tantalum is a transition metal in Group 5 (VB) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Tantalum is one of the most inert metals known.

How much is tantalite worth?

What is tantalite concentrate?

Tantalum concentrate is one of the primary feed sources used by processors to produce tantalum capacitor powders and metallurgical products. The concentrate is also used to produce pure tantalum pentoxide (Ta2O5) primarily utilized in the production of optical glass and lithium niobate.

How are tantalite and columbite related to each other?

Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.

How did the mineral tantalite get its name?

The name of this mineral is said to be related to a Greek myth regarding one of the sons of Zeus called Tantalus. It was said that after Tantalus had died, he was eternally punished by being made to stand in a pool of water, located under a fruit tree with low hanging branches with fruit on them.

What are the different colors of tantalite stone?

It is more commonly a manganese rich stone that comes in a number of colors. This includes deep black, brown, brownish-black, red, orange red and reddish brown and it may be found combined with other minerals such as Hematite.

What are the properties of the element tantalum?

Tantalum (Ta) itself is a heavy (specific gravity of 16.6) blue-grey metallic element with a melting point of 2,996°C. It has excellent corrosion resistance, good ductility and is resistant to most acids.
