Neodymium
Neodymium (Nd) is a soft, silvery-white rare earth element and the fourth in abundance among the lanthanides. It has a melting point of 1 024 °C and is known for its strong magnetic properties in alloyed form. Neodymium is primarily obtained from monazite and bastnäsite ores and refined via solvent extraction and ion exchange processes.
Goodfellow's high-purity Neodymium products are designed to meet the exacting requirements of advanced research and industrial applications. Available in forms such as foil, powder, rod, and sputtering target, neodymium is valued for its exceptional magnetic properties and unique electronic configuration. This rare earth metal exhibits strong ferromagnetic behavior when alloyed with iron and boron, creating powerful permanent magnets. Neodymium finds critical applications in the renewable energy sector, consumer electronics, and automotive industries. It plays a vital role in wind turbine generators, enhancing their efficiency and power output, and is crucial in the production of electric vehicle motors, contributing to the advancement of sustainable transportation. Goodfellow's neodymium products support cutting-edge research in areas such as magnetic resonance imaging (MRI) technology and next-generation data storage systems. Their distinctive properties make them indispensable for scientists and engineers advancing materials science, particularly in applications requiring strong magnetic fields and miniaturization of electronic devices.
