Dysprosium oxide (Dy₂O₃) is a high-quality oxide of the rare earth metal dysprosium and is one of the important compounds of the rare earths. It is a fine powder in pastel yellowish-green to white color, which is slightly hygroscopic. Dysprosium oxide is characterized by its high thermal stability and very good chemical resistance. It is practically insoluble in water, but dissolves well in acids to form dysprosium salts.

The economic and technical use of dysprosium oxide is diverse. It is mainly used as an additive in specialty glass, ceramics, and phosphors. Due to its paramagnetic and optical properties, it is used in magneto-optical materials, lasers, and as a dopant for optical fibers. In magnet technology, it serves as a starting material for the production of high-performance permanent magnets. In addition, it is used in the manufacture of metal halide lamps. All of this makes dysprosium oxide a valuable raw material for high-tech applications.

The following applications of dysprosium oxide are particularly noteworthy:

• Production of specialty glass and ceramics;
• as a dopant in laser materials and phosphors;
• in permanent magnets and magnetostrictive alloys;
• as an additive in optical coatings and metal halide lamps;
• in catalysts and high-tech ceramics.

Dysprosium oxide has the following properties:

• high thermal stability (melting point approx. 2408 °C);
• very good chemical resistance;
• paramagnetic properties;
• insoluble in water, soluble in acids;
• slightly hygroscopic;
• excellent optical and magneto-optical properties.
