Niobium (Nb) Pellets Evaporation Materials

Niobium, formerly columbium, is a chemical element with symbol Nb (formerly Cb) and atomic number 41. It is a soft, grey, ductiletransition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite. It has a density of 8.58 g/cc, a melting point of 2,468°C, and a vapor pressure of 10-4 Torr at 2,287°C. Haohai Metal offers a full suite of Niobium evaporation pellets at competitive prices. Custom sizes and materials can also be fabricated to meet your requirements.

Niobium (Nb) Pellets Evaporation Materials


General


Niobium, formerly columbium, is a chemical element with symbol Nb (formerly Cb) and atomic number 41. It is a soft, grey, ductiletransition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite. Niobium is used in various superconducting materials. These superconducting alloys, also containing titanium and tin, are widely used in the superconducting magnets of MRI scanners. Other applications of niobium include welding, nuclear industries, electronics, optics, numismatics, and jewelry. In the last two applications, the low toxicity and iridescence produced by anodization are highly desired properties. It has a density of 8.58 g/cc, a melting point of 2,468°C, and a vapor pressure of 10-4 Torr at 2,287°C.
