Neodymium, with the symbol Nd and atomic number 60, is a versatile rare earth element known for its strong magnetic properties. It’s a key component of neodymium-iron-boron (NdFeB) magnets, which are the most powerful permanent magnets available. These magnets are essential in modern technologies, including wind turbines, hard disk drives, and electric vehicle motors.
Discovered by Austrian chemist Carl Auer von Welsbach in 1885, neodymium is extracted mainly from bastnäsite and monazite ores. The metal itself is silvery-white and tarnishes when exposed to air, forming an oxide layer. It’s relatively abundant, making up about 38 parts per million of the Earth’s crust, similar to copper.
Neodymium’s magnetic strength, even in small amounts, contributes significantly to reducing the size and improving the performance of electronic devices. It also plays a role in manufacturing high-powered infrared lasers for cutting and welding, as well as in glass coloring, where it adds purple hues. Despite being termed a rare earth element, neodymium is widely utilized due to its relative abundance and potent properties.
