설명

일반 설명

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.

애플리케이션

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.
