Dysprosium titanate (Dy2Ti2O7) is an inorganic compound, a ceramic of the titanate family, with pyrochlore structure.

Dysprosium titanate, like holmium titanate and holmium stannate, is a spin ice material. In 2009, quasiparticles resembling magnetic monopoles were observed at low temperature and high magnetic field.[2][3]

Dysprosium titanate (Dy2TiO5) is used since 1995 as material for control rods of commercial nuclear reactor.[4]
