Facts About Tantalum

Atomic Number: 73 Atomic Symbol: Ta Atomic Weight: 180.94788 Melting Point: 5,462.6 F (3,017 C) Boiling Point:9,856.4 F (5,458C)

Sources of tantalum

Separating tantalum from niobium requires either electrolysis, reduction of potassium fluorotantalate with sodium, or reacting the carbide with oxide.

Natural tantalum contains two isotopes while twenty-five isotopes are known to exist.

Uses of tantalum

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.

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.

Tantalum oxide is used to make special glass with a high index of refraction for items such as camera lenses.

cost for tantalum: Tantalum Demand Strengthens but Prices Continue to.

the fourteenth edition of its Tantalum: Global Industry, Markets & Outlook 2020 report which analyses supply, demand, trade and prices, and includes forecasts out to 2028.

The report paints a positive picture for demand growth with strong increases from the superalloy sector (driven by the aerospace and industrial gas turbines) and recovery in the major market of capacitors (driven in the short-term by expansion into traditional ceramic capacitor applications - of which there is a huge shortage - and in the long-term by the increasing electrification of our vehicles and homes).

Roskill expects growth in almost all of the major applications with total demand growing by 4-5%py between 2018 and 2028.

The price of tantalum continues to fall, however, with prices declining from their mid-2018 peak of more than US$100/lb to around US$82/lb by mid-November (as reported by Asian Metal for CIF China, 30% Ta2O5).

Roskill forecasts prices to fall further in 2019 as the industry is poised to see a sudden influx of new low-cost tantalum supply as a by-product from Australian lithium miners.

Australia currently accounts for around 5% of primary tantalum supply, but this could grow to as high as 33% by 2021 based on Roskill's upper-level forecast for supply growth.

Growth could come at the expense of African artisanal production, which currently accounts for the majority of global supply.

Roskill's new report profiles the major producers of tantalum and breaks down both supply and demand by country.

Projects that may soon come on-line and contribute to tantalum supply are explored in detail, including Australian lithium projects looking to supply via by-product streams.

In 2018, Pilbara Minerals and Tawana Resources/Alliance Mineral Assets have both begun to ship tantalum by-product from Australia and are likely to ramp-up their production in the coming years;

other projects could also come on-line in Australia to add to the new supply.

Pilbara Minerals has just committed itself to a large expansion program, to be commissioned in 2019.

Australian supply offers a potentially lower cost and more stable alternative to the African artisanal supply from the Central African Great Lakes region that currently dominates the market, accounting for around 38% of primary tantalum supply in 2018.

Production from this region has long been associated with conflict mining, although the situation has improved in recent years with the introduction of the Dodd-Frank Act, government- and consumer-led schemes to fund due diligence, bag-tagging schemes to improve tractability through the supply chain, and now plans to use blockchain technology.

The EU will introduce its new Conflict Minerals Regulation in 2021 to match international levels of supply chain responsibility.

Tantalum is typically used in niche high-performance applications where there is little threat of substitution.

Consumers are, therefore, more concerned with the availability and sustainability of supply than price.

With growing demand and the potential for a shift towards a more sustainable supply from a number of news sources, the tantalum industry looks set for substantial change over the next decade.

Tantalum - an overview

The separation of niobium and tantalum powders is accomplished by dissolving the ore or slag in hydrofluoric acid to produce hydrofluotantalic acid and hydrofluoniobic acid.

These can be separated through chemical extraction, which takes advantage of their different solubilities in particular acid solutions.

Once separated, the hydrofluotantalic acid is reacted with potassium to produce K2TaF7.

This salt is reacted with molten sodium to produce pure tantalum and water-soluble potassium and sodium salts.

The tantalum can be sintered, but the sintered bars are usually melted for further purification and to produce ingots of higher density.

Electron beam melting is the most common melting practice, but vacuum arc remelting is also used, especially in the production of alloys, since it provides better mixing.

Because tantalum is ductile at room temperature, it can be processed without heating the workpiece.

This provides a great advantage over the tungsten and molybdenum processes described above since working these metals at high temperatures always results in some loss of material through oxidation.

The first steps in working the metal are usually forging operations at room temperature.

Forging can break up the large cast grain size and begin to shape the material.

This process can be followed by rolling, swaging, or wire drawing.

Recrystallization of the worked material usually occurs above 1273 K, and appropriate anneals must be performed during processing to prevent overwork of the material.

The largest use of tantalum is for capacitors.

The capacitor is made of tantalum oxide with a tantalum wire used to connect the capacitor to the circuit.

Because of its excellent corrosion resistance, tantalum is often used as a sheet liner for acid containment tanks.

It is also used in shell and tube heat exchangers.

Another important use of tantalum is in the defense industry.

Its high density allows it to be used for various types of penetrators.

Alloying of the material with tungsten increases its density and strength.

Price History of Tantalum

The price is determined after negotiations between the seller and the buyer, although it’s estimated that the starting point for these negotiations is at $123.61 per kilo.

There is some persistent demand for the metal, but the supply picture is a bit murky.

This has added to the difficulty in pegging the price of the metal.

In 2010, it was reported that Brazil and other places in South America produced about 40% of the global annual supply, with Australia coming second at 21%.

Central Africa accounts for less than 10%.

More importantly, it’s been estimated that there are only less than 50 years of supply left based on current extraction rates from mines.

This has emphasized the need for greater recycling.

The price of the tantalite is very much dependent on the demand as well.

The price of tantalite ore rose from about $75 per kilo in 2010 to more than $270 per kilo in 2011 and 2012.

But the price has dropped since then.

However, some experts point to expected growth in the electronics, aerospace, and power industry to boost the price back up.

can therefore not assume any responsibility or be held liable in any way in relation to the information published on these websites.

To calculate the value of a tantalum mineral, the main principle is that only the quantity of Ta2O5 contained is paid for, not the whole bulk of the material.

Basically the weight of the material is multiplied by the percentage grade e.g. 30%, then multiplied by the pricing rate of X$/lb Ta2O5.

Note that while our industry statistics have moved to metric units, the traditional valuation basis of $/lb Ta2O5 contained is likely to continue.

[Value tantalite] = weight of material x 30% [x conversion to lb if necessary] x X$/lb Ta2O5

In theory, it does not matter whether the material is 30% or 40%, by applying the percentage the quantity paid for is automatically adjusted;

sliding scales according to grade are not known.

There may possibly be fixed discounts or premiums for grades significantly below or above the 30% to 50% range.

The content of Nb2O5 in tantalum minerals is ignored as its contribution would generally be minimal due to the price difference between Nb and Ta.
