Dysprosium(III) hydroxide is an inorganic compound with the chemical formula Dy(OH)₃.

Chemical properties

Dysprosium(III) hydroxide reacts with acids and produces dysprosium(III) salts:

Dy(OH)₃ + 3 H → Dy + 3 H₂O

Dysprosium(III) hydroxide decomposes to DyO(OH) at elevated temperatures. Further decomposition produces Dy₂O₃. The reactions are:

Dy(OH)₃ → [_299.8 °C] DyOOH + H₂O

2 DyOOH → [_386.6 °C] Dy₂O₃ + H₂O
