Product Infomation
Product Name Niobium (Nb) Microspheres, 1 μm
Catalog Number IMM-MM-014
Physical Specs 1 μm
Description Niobium (Nb) Microspheres are high-purity refractory niobium microspheres with exceptional corrosion resistance, high melting point and biocompatibility, ideal for superalloy development, electronic components and biomedical implant materials.
Applications Superconductivity: Niobium is the element with the highest critical temperature among those exhibiting superconducting properties. Alloys made from niobium have critical temperatures as high as 185.0 to 210 K, making them the most important superconducting materials currently available; High-temperature alloys: A significant portion of the world’s niobium is used in the form of pure metal or high-purity niobium-iron and niobium-nickel alloys for the production of nickel-, chromium-, and iron-based high-temperature alloys. These alloys are used in jet engines, gas turbine engines, rocket components, turbochargers, and heat-resistant combustion equipment; Steel: Among the various microalloying elements in steel, niobium is the most effective. Its effect is so significant that simply having a high concentration of niobium atoms in the iron matrix is sufficient to improve the properties of the steel. In fact, adding just 0.001%–0.1% niobium to steel is sufficient to alter its mechanical properties; Coins: In coinage, niobium is sometimes used alongside gold and silver in commemorative coins as a precious metal; other niobium (or niobium alloyed with 1% zirconium) serves as a sealing material for high-pressure sodium lamp arc tubes, as niobium’s coefficient of thermal expansion is very similar to that of sintered alumina arc lamp ceramic materials.
