use

Mainly used for manufacturing microwave magnetic materials and important military materials (single crystal; composite oxides such as yttrium iron garnet and yttrium aluminum garnet), also used as optical glass, ceramic material additives, and high-brightness phosphors for large-screen TVs And other picture tube coatings. It is also used to manufacture film capacitors and special refractory materials, as well as magnetic bubble materials for high-pressure mercury lamps, lasers, and storage components. Adding yttrium oxide during sintering can effectively reduce the grain size of tungsten alloys.
