Thank you for watching our elements. Working with the "building blocks" of our universe is more than dusty science, it is in fact a deep and sometimes expensive passion. Advanced Element collectors want special items rather than uniformed series. We mainly produce custom made element samples on request.
My slogan is "The purer, the better.." - If you really want to know the physical and chemical properties of a material, then even the purest is just good enough. Here we sell incomparable quality and unique element samples at lowest prices. If you are not satisfied, you get your money back!
High purity Niobium disc Ø7/8" x 0.5mm - 99.95% purity
For Laboratory, high temperature applications etc.
Different sizes available (see zoom picture)
Discovered in 1801 by C. Hatchett in London, England. Niobium is a silver colored metal which is generally found in conjunction with tantalum, the two elements being separated by fractional crystallization of their respective fluoro-complexes. It has an abundance of 20 ppm in the earth's crust. As a pure metal, is very reactive and forms an extremely stable oxide when exposed to air which enhances its corrosion resistance. Niobium will react with a variety of non-metals at elevated temperatures. Niobium and its alloys have high melting points and are, therefore, used in high temperature engineering products (for use at temperatures in excess of 1200C). It is also used as an alloying agent for certain steels where it greatly improves the strength of the resulting material. Niobium also finds applications in atomic reactors due to its corrosion resistance and, when combined with either tin (Nb3Sn) or zirconium, it has a high degree of superconductivity.
