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. In laboratory animals, inhalation of niobium nitride and/or pentoxide leads to scarring of the lungs at exposure levels of 40 mg/m3.
What does niobium do for steel?
According to USGS, nearly 80 percent of niobium is used in the steel industry to create high-strength low-alloy steels. The use of niobium in these alloys increases the steels’ mechanical and high-temperature strength, toughness, and corrosion resistance.
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.
Who produces niobium?
Brazil
An example of a super alloy is Inconel which is made up of 3.1% of niobium. Niobium is quickly becoming a “strategic metal” due to its importance in defense and aerospace….The World’s Largest Producers of Niobium.
| Rank | Country | Production of Niobium (Metric Tons) |
|---|---|---|
| 1 | Brazil | 40,000 |
| 2 | Canada | 4,167 |
| 3 | Australia | 200 |
| 4 | Rwanda | 80 |
What country has the most niobium?
Global columbium reserves by country 2020 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.
Why is niobium valuable?
Niobium is used in the production of high-temperature resistant alloys and special stainless steels, as well as high strength low alloy carbon steels. Demand for niobium is strengthening, mainly on the back of increased use in steel-making and electronics.
Where can I get niobium?
Niobium has no known biological role. The main source of this element is the mineral columbite. This mineral also contains tantalum and the two elements are mined together. Columbite is found in Canada, Brazil, Australia, Nigeria and elsewhere.
What does niobium look like?
Characteristics: Niobium is a shiny, white, ductile metal. In air an oxide layer forms whose color depends on its thickness. Shades of blue, green and yellow are typical.
Who buys niobium?
Exotech
Exotech buys and sells Niobium (Nb) worldwide for use in applications including superalloys, superconducting alloys, rocket nozzles, chemical equipment, medical devices, thin films and electronic components.
Is niobium rare or common?
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.
Can niobium be recycled?
The typical recycling process of niobium is usually by re-melting. One of the main barriers to improving the recycling rate is not enough attention is given to the composition of the steel scrap during recycling. Much niobium is diluted to lower grade steel and or is lost in the slag phase.
