· DyHO2

DyHO2 is a dysprosium oxyhydroxide ceramic compound belonging to the rare-earth hydroxide oxide family. This material is primarily studied in research contexts for applications requiring high stiffness, thermal stability, and chemical resistance characteristic of rare-earth ceramics. DyHO2 is notable for its potential in high-temperature structural applications and specialized environments where dysprosium's neutron absorption and thermal properties provide advantages over conventional oxide ceramics.
