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.[1] The reactions are:[2]

Dy(OH)3 → [299.8 °C] DyOOH + H2O
2 DyOOH → [386.6 °C] Dy2O3 + H2O
