yttrium oxide is mainly used as a magnetic material for microwave processing and an important material for military industry (single crystal; yttrium garnet, yttrium aluminum garnet and other composite oxides), also used as an optical glass, ceramic material additive, high-brightness phosphor for large-screen TV And other tube coatings. It is also used in the manufacture of film capacitors and specialty refractory materials, as well as magnetic foam materials for high pressure mercury lamps, lasers, storage elements and the like. The addition of Yttrium oxide during sintering can effectively reduce the grain size of the tungsten alloy.
