Molecular formula: Y₂O₃

Appearance characteristics: white and slightly yellow powder, insoluble in water and alkali, soluble in acid.

Usage: Mainly used for manufacturing microwave magnetic materials and important military materials (single crystal; composite oxides such as yttrium iron garnet, yttrium aluminum garnet), also used as optical glass, ceramic material additives, large-screen TVs Use high-brightness phosphors for 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 the tungsten alloy.
