Yttrium oxide

Molecular formula: Y2O3

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

Uses: Mainly used for the manufacture of microwave magnetic materials and military important materials (single crystal; yttrium iron garnet, yttrium aluminum garnet and other composite oxides), also used as optical glass, ceramic material additives, large-screen TV with high brightness fluorescent powder picture tube coating. It is also used in the manufacture of film capacitors and special refractory materials, as well as magnetic bubble materials for high-pressure mercury lamps, lasers, storage components, etc. Adding yttrium oxide during sintering can effectively reduce the grain size of tungsten alloy.
