General description

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/cm3. 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 production of synthetic fuels among other applications.

Application

Holmium(III)oxide can be used as:
  • A starting material to prepare Ho2O3-PVAfilm for generating stable Q-switching pulses in a thulium-doped fiber laser(TDFL) cavity.
  • A catalyst for oxidative coupling of methane.
It can also be used as a dopant in the preparation of:
  • Cadmium lead borate glasses.
  • Diamond/copper composites to eliminate interfacial defects through the spark plasma sintering (SPS) method.
