Dysprosium titanate (Dy₂Ti₂O₇ or Dy₂TiO₅) is an inorganic compound, specifically a ceramic of the titanate family. Two common phases of this compound exist with differing properties: Dy₂Ti₂O₇ and Dy₂TiO₅. Dysprosium titanate is commonly used throughout the nuclear industry in nuclear control rods and as a host for nuclear waste.^[2]^[3]
