yttrium oxide;yttria

1. To make microwave use magnetic materials and weapons, with important material is used for optical glass. Yttrium oxide can increase the refractive index of a special glass, reduce dispersion index, used as a giant TV screen, with high brightness tube fluorescent powder and other coatings. Used in the manufacture of film capacitor and special refractory and high pressure mercury lamp, laser, storage element such as magnetic materials. Also used in synthetic ruby laser crystal, superconducting materials and etc. Lanthanide optical glass and resistance to high temperature and radiation optical glass additives. In silicon nitride, zirconia and piezoelectric ceramics, engineering ceramics, such as photovoltaic, semiconductor ceramic ceramics and ceramic capacitors, thermistors, etc is an important additive in the functional ceramics. Also used in the manufacture of film capacitor, special refractory material, and high pressure mercury lamp, laser, storage element such as bubble material.

2. It is mainly used for the preparation of new type of magnetic material yig yttrium aluminum garnet and solid laser material, and television, ultrashort afterglow phosphor and phosphor X-ray intensifying screen with phosphors and fluorescent phosphors. Lanthanide optical glass and resistance to high temperature and radiation optical glass additives. In the silicon nitride, zirconia ceramic engineering ceramics and functional ceramics of piezoelectric ceramic, photoelectricity, semiconductor ceramic, thermistor ceramics and ceramic capacitor is an important additive. Also used for the preparation of hydrogen storage materials, superconducting materials and artificial stones.
