Thulium(III) hydroxide


Thulium hydroxide is an inorganic compound with the chemical formula Tm3. It can be prepared by the addition of ammonia solution to a solution containing a soluble thulium salt.

Chemical properties

Thulium hydroxide reacts with acids and produces thulium salts:
Thulium hydroxide decomposes to TmO at elevated temperature. Further decomposition produces Tm2O3.
Thulium hydroxide reacts to form thulium acetylacetonate in the presence of absolute ethanol and acetylacetone. The product precipitates upon cooling of the solution.
