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⁺ → Dy³⁺ + 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 + H
2O

2 DyOOH → [
386.6 °C] Dy
2O
3 + H
2O
