use
1. Manufacture magnetic materials for microwave and important materials for military industry, and also used as optical glass. Yttrium oxide can increase the refractive index of special glasses, reduce the dispersion index, and be used as high-brightness phosphors for large-screen TVS and other picture tube coatings. Used in the manufacture of film capacitors and special refractory materials, as well as high pressure mercury lamps, lasers, storage components and other magnetic bubble materials. Also used in artificial gem laser crystals, superconducting materials and so on. It is an additive to lanthanide optical glass and high temperature and radiation resistant optical glass. It is an important additive in engineering ceramics such as silicon nitride and zirconia, as well as functional ceramics such as piezoelectric ceramics, photoelectric ceramics, semiconductor ceramics, thermistor ceramics and capacitor ceramics. It is also used in the manufacture of film capacitors, special refractory materials, and magnetic bubble materials for high pressure mercury lamps, lasers, storage components, etc.
2. It is mainly used for the preparation of new magnetic materials yttrium iron garnet and solid laser materials yttrium aluminum garnet, as well as TV phosphors, ultra-short persistence phosphors, X-ray sensitizing screen phosphors and fluorescent lamps. It is an additive to lanthanide optical glass and high temperature and radiation resistant optical glass. It is an important additive in engineering ceramics such as silicon nitride, zirconia ceramics and functional ceramics such as piezoelectric ceramics, photoelectric ceramics, semiconductor ceramics, thermistor ceramics and capacitor ceramics. In addition, it is also used to prepare hydrogen storage materials, superconducting materials and artificial gems.
