Applications
| Application | Role | Significance |
|---|---|---|
| High-temperature NdFeB magnets | Dy/Tb substitution at the (Nd,Dy)2Fe14B grain boundary | ~90% of Dy demand. Without Dy, NdFeB magnets demagnetise above ~100 °C. Required for EV traction motors, wind turbines operating at elevated temperatures. |
| Magnetostrictive alloys | Tb–Dy–Fe (Terfenol-D) | Ultrasonic transducers, sonar projectors, precision actuators |
| Nuclear control rods | Dy2O3 in TiO2 ceramic absorbers | Long-life PWR control rod absorbers; Dy has high thermal-neutron capture cross-section |
| Dysprosium iodide lamps | DyI3 in metal-halide arc lamps | Studio motion-picture lighting, stadium lighting (legacy use) |
| Dosimeters | CaSO4:Dy and Dy-doped fluorides | Thermoluminescent dosimetry for radiation monitoring |

Dysprosium is the most expensive of the routinely traded rare earths. The auto-rendered table shows tracked retail listings — institutional procurement should reference Argus or Asian Metal benchmarks rather than gram-scale retail.

Important Notes
Export controls in force
Dy is one of the seven medium and heavy rare earths controlled under MOFCOM/GAC No. 18/2025 [2]. Critically, the order extends to finished NdFeB magnet rotors containing Dy at material thresholds — not just oxide, metal, or alloy forms.
EV motor dependency
Every NdFeB EV traction motor uses 100–200 g of Dy/Tb to maintain coercivity above the operating temperature of the rotor. Western automaker exposure is direct: a Dy supply disruption would halt EV motor production within months.
Grain-boundary diffusion saves Dy
Modern manufacturing uses GBD (grain-boundary diffusion) to deposit Dy/Tb only at the magnet grain surfaces, cutting required Dy mass by 30–50% versus uniform alloying. Hitachi Metals (now Proterial), TDK, and Chinese magnet houses all use GBD processes.
