Dysprosium
Dysprosium (Dy) is a rare earth element known for its high magnetic susceptibility, strength at elevated temperatures, and resistance to demagnetization. Dysprosium features a melting point of 1412 °C and a relatively high density. It is typically extracted from monazite and bastnäsite ores and refined through solvent extraction and ion exchange processes.
Goodfellow's pure Dysprosium product line is available in forms such as foils, powders, rods, and sputtering targets. This rare earth metal is crucial in industries such as electronics, renewable energy, and nuclear power. Dysprosium plays a vital role in the production of powerful permanent magnets for electric vehicles and wind turbines, as well as in the development of control rods for nuclear reactors. Goodfellow's dysprosium products are instrumental in driving technological advancements, supporting cutting-edge research in areas such as data storage systems and high-intensity lighting technologies. Its distinctive combination of properties makes it essential for scientists and engineers pushing the boundaries of materials science, particularly in applications requiring high magnetic strength and thermal stability.
