| Dysprosium Oxide Dy2O3 |
| A white, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers and dysprosium metal halide lamps. |
| Holmium(III) oxide (Ho2O3) and Dysprosium(III) oxide (Dy2O3) are the most powerfully paramagnetic substances known. |
| Terfenol-D Tb0.3Dy0.7Fe1.9 |
| The alloy has an extremely high magnetostriction; it expands and contracts in magnetic fields. It sees application in magnetomechanical sensors, actuators, and acoustic and ultrasonic transducers or in naval sonar systems. |
| Developed in the 1950's at the Naval Ordnance Laboratory in America. It is named after terbium, iron (Fe), Naval Ordnance Laboratory (NOL), and the D comes from dysprosium. |
