1. Fluorescent powder: Europium oxide is an important activator for manufacturing red fluorescent powder for color televisions, and is also used as fluorescent powder for high-pressure mercury lamps. In addition, it can also be used as stimulated emission fluorescent powder for new X-ray medical diagnostic systems.
2. Optical materials: Europium oxide can be used to manufacture colored lenses and optical filters, changing the direction and color of light propagation.
3. Magnetic materials: Due to their special magnetic properties, europium oxide can be used to manufacture magnetic bubble storage devices.
4. Chemical raw materials: Europium oxide has various applications in the chemical industry, such as manufacturing dyes, rubber vulcanization accelerators, drugs, pesticide fungicides, amino resins, ethylenediamine urea formaldehyde resins, metal chelating agents EDTA, etc.
5. Other applications: Europium oxide can also be used as a solvent for fibrin and other substances.
