Dysprosium oxide (DyO2) is a rare-earth ceramic compound belonging to the lanthanide oxide family, characterized by high density and strong elastic properties. It is primarily used in advanced nuclear applications, including control rods and neutron absorbers in nuclear reactors, as well as in specialized optical and thermal barrier coating systems for high-temperature aerospace components. DyO2 is valued for its combination of excellent neutron absorption cross-section, thermal stability at extreme temperatures, and chemical inertness, making it an alternative to more conventional rare-earth ceramics when superior radiation shielding or thermal cycling resistance is critical.
