Niobium Powder, CAS No 7440-03-1
Niobium powder is a fine, gray metallic powder composed of small particles of niobium. It is commonly used as a raw material for producing various niobium-based products, such as wires, rods, sheets, and tubes. Niobium powder is also used in the production of superalloys, which are used in high-temperature applications, such as aerospace and power generation. Additionally, niobium powder has applications in the electronics industry, where it is used to make capacitors, superconductors, and other electronic components. Niobium powder can be produced through a variety of methods, including chemical reduction, thermal decomposition, and electrolysis.
