How much does niobium cost per pound?
Published niobium concentrate prices have remained at US$16/lb , as of mid-March 2018, while tantalum concentrate prices have risen to US$93/lb.
What is niobium used for?
Niobium is used in alloys including stainless steel. It improves the strength of the alloys, particularly at low temperatures. Alloys containing niobium are used in jet engines and rockets, beams and girders for buildings and oil rigs , and oil and gas pipelines. This element also has superconducting properties.
Can I buy niobium?
PERFECT SPECIFICATIONS & SIZE: Exotech is a manufacturer of pure Niobium. We produce Niobium in purities ranging from 99.95% – 99.99%. Each piece of our pure Niobium measures 25 mm (1′′) or smaller and you can purchase this with a minimum of 250 grams.
What is the price of tantalum per kilo in 2020?
In 2020, the price of tantalum was approximately 158 U.S. dollars per kilogram of Ta2O5 content.
What country has the most niobium?
As of 2020, Brazil had the world’s largest reserves of niobium by a large margin, amounting to 16 million metric tons, compared to niobium reserves of roughly 170,000 metric tons in the United States.
Is niobium rare?
Niobium is a rare metal found in numerous locations around the world in rocks of volcanic origin. It is relatively difficult to find and is produced from pyrochlore and tantalite ores, and as a by-product of mining for other minerals.
What is today’s price of silver?

Is niobium poisonous or hazardous?
Niobium and its compounds may be toxic (niobium dust causes eye and skin irritation) , but there are no reports of human being poisoned by it. Apart from measuring its concentration, no research on niobium in humans has been undertaken. Niobium, when inhaled, is retained mainly in the lungs, and secondarily in bones.
Is niobium a precious metal?
Niobium features many of the characteristics of precious metals . It is rare, difficult to refine, and highly resistant to chemical attack. It is malleable and hypoallergenic – and its price is above the current silver spot. You might call it a “semiprecious” metal.
Why is niobium added to steel?
1. Niobium added to steel refines remarkably the cast structure and austenite structure of steel . ... With an addition of niobium, the coarsening temperature of austenite-grains will rise. For example, in the case of 0.03 to 004% niobium addition, the coarsening temperature rises by approximately 160°C and reaches 1050°C.
Is niobium radioactive?
There is only one stable isotope of niobium, namely ^Nb. All other niobium isotopes, includingw Nb, are radioactive . The radioactive isotopes of niobium have half-lives ranging from a few seconds (104 Nb, 1.0 seconds) to millions of years (^Nb, 37,000,000 years).
Is tantalum stronger than gold?
#1.
Tantalum, on the other hand, is much more flexible and less likely to break under pressure. However, it’s good to know that both metals are much harder and scratch-resistant than gold or platinum , yet much more affordable.
Is tantalum more expensive than gold?
For such a rare metal, tantalum is priced reasonably. However, unlike other industrial metals like ceramic, titanium, tungsten or cobalt, tantalum is much pricier . It’s not as expensive as gold or platinum, but it’s not exactly cheap either.
Why is tantalum so expensive?
Modern microelectronics is developing because of tantalum . ... The usage of tantalum allowed to replace aluminum for copper as an interconnection material. Tantalum is a barrier preventing copper diffusion into silicon-oxide-based dielectrics.
