Nano-Dysprosium Oxide: The "Optomagnetic Elf" Illuminating High-End Technology

In the rare earth family, nano-dysprosium oxide (Dy₂O₃) has become a key material in high-end technology fields due to its unique optomagnetic properties. This white powdery nano-sized compound, usually with a particle size between 20-100 nanometers, has better physical and chemical properties than ordinary dysprosium oxide.

In the field of magnetic materials, nano-dysprosium oxide is an indispensable "performance stabilizer" for high-performance NdFeB permanent magnets. It can significantly improve the coercivity and temperature stability of magnets, allowing permanent magnets to maintain strong magnetic force in high-temperature environments. In new energy vehicle drive motors, permanent magnets added with nano-dysprosium oxide can withstand working temperatures above 150℃, ensuring that the motor does not experience magnetic attenuation during long-term high-load operation. According to industry data, each new energy vehicle drive motor requires about 500 grams of nano-dysprosium oxide, which is also an important reason for it to become a core material in the new energy industry.
