Chemical formula Y2O3, white yellowish powder, insoluble in water and alkali, soluble in acid. Mainly used for the manufacture of microwave magnetic materials and Single crystal; Yttrium iron garnet, yttrium aluminum garnet and other composite oxides), It is also used as an additive for optical glass, ceramic materials, high brightness phosphor for large screen TVS and other picture tube coatings.
Application
Mainly used for the manufacture of magnetic materials for microwaves and important materials for industry (single crystal; composite oxides such as yttrium iron garnet, yttrium aluminum garnet, etc.), also used as optical glass, ceramic material additives, high-brightness phosphors for large-screen TVs and other picture tube coatings. It is also used in the manufacture of film capacitors and special refractory materials, as well as magnetic bubble materials for high-pressure lasers, storage components, etc. The addition of yttrium oxide during sintering can effectively reduce the grain size of the tungsten alloy. Manufacture of light sources in infrared spectrometers, hoods for acetylene lamps and gas lamps, phosphors for color TV tubes, stabilizers for zirconia refractories, phosphors, synthetic gemstones, laser crystals, superconducting materials, and many cutting-edge applications in the electronics industry.
