Charged EVs | US-based Power Fuels’ Dy oxide qualifies to be used in EV motor everlasting magnets

Dysprosium (Dy) oxide produced by US-based vital uncooked supplies provider Power Fuels has handed preliminary purity and high quality assurance and high quality management benchmarks at an unnamed South Korean automotive producer for uncommon earth everlasting magnet manufacturing.

Power Fuels produced the primary kilogram of Dy oxide at its White Mesa Mill in Utah in August 2025, and output has to this point totaled roughly 29 kg at pilot scale. The power achieves purities of 99.9%, exceeding the automotive specification of 99.5% purity.

Dy oxide is a key additive in neodymium-iron-boron (NdFeB) that improves sturdiness and magnetic efficiency in everlasting magnets utilized in motors to energy EVs, hybrid autos, robotics and different automotive and business purposes.

The corporate beforehand introduced that its neodymium-praseodymium (NdPr) oxide has additionally been certified to be used in NdFeB magnets.

Power Fuels has began piloting terbium (Tb) oxide manufacturing on the facility and expects to have kilogram-scale samples accessible for qualification in early 2026. Tb oxide can also be utilized in everlasting magnets that may stand up to excessive working temperatures in EVs and protection techniques.

Following the Tb oxide pilot, the corporate plans to start piloting gadolinium (Gd) after which samarium (Sm) oxide manufacturing. It’s continuing with plans to construct the infrastructure wanted to provide Dy, Tb, and probably Sm oxides at business scale on the White Mesa Mill. This might give it annual capability to provide as much as 48 metric tons (tonnes) of Dy oxide and 14 tonnes of Tb oxide, topic to accessible feed.

“Manufacturing of dysprosium oxide that meets stringent magnet specs is one other key milestone within the firm’s vital supplies technique, demonstrating Power Fuels’ distinctive and quickly increasing capabilities within the uncommon earth sector, and particularly our means to provide high-purity separated ‘heavy’ uncommon earth oxides from monazite at our White Mesa Mill in Utah,” stated Mark S. Chalmers, CEO of Power Fuels.
