Holmium (III) oxide, or holmium oxide is a chemical compound of the rare-earth element holmium and oxygen with the formula Ho 2 O 3. Together with dysprosium (III) oxide (Dy 2 O 3), holmium oxide is one of the most powerfully paramagnetic substances known.

Holmium (III) oxide is a white crystalline powder and is a rare-earth metal oxide. Holmium (III) oxide is a highly stable and resistant to chemical attack. It has a high melting point of 2,380 °C and a high density of 8.8 g/cm 3. Holmium (III) oxide is used as a raw material in the production of holmium and holmium alloys, as a magneto strictive material in sensors, and a catalyst in the ...
