Holmium oxide (Ho₂O₃) is a high-quality oxide of the rare-earth element holmium and is among the important compounds of the rare earths. It is available as a fine powder in a yellowish-beige to light brown color. Holmium oxide is distinguished by its exceptional optical properties, high thermal stability, and good chemical resistance. It is insoluble in water, but dissolves well in acids to form holmium salts.

The economic and technical use of holmium oxide is primarily based on its strong optical and paramagnetic properties. It is mainly used as a dopant in laser materials, specialty glasses, and optical fibers. Holmium oxide gives glass a characteristic yellow-pink coloration and is used to produce infrared-absorbing glasses and optical filters. It is also used in ceramics, in phosphors, as well as in the production of highly precise optical components and magnetic materials. All of this makes holmium oxide a valuable raw material for the laser, optics, and high-technology industries.

The following applications of holmium oxide are particularly noteworthy:

• Dopant in laser materials and optical fibers;
• Production of specialty glasses and infrared-absorbing glasses;
• Optical filters and magneto-optical materials;
• In phosphors and luminescent materials;
• In ceramics and high-tech optical components.

Holmium oxide is characterized by the following properties:

• Yellowish-beige to light brown fine powder;
• High thermal stability (melting point approx. 2415 °C);
• Excellent optical and paramagnetic properties;
• Insoluble in water, soluble in acids;
• Strong absorption in the infrared range;
• High chemical resistance.
