Application

Yttrium oxide is mainly used to manufacture magnetic materials for microwave applications and important materials for military use, such as single crystals, yttrium iron garnet, yttrium aluminum garnet and other composite oxides.
These composite oxides have good high-frequency performance and can be used as important materials for microwave magnetic materials and military communication engineering.
It is also used as an additive for optical glass and ceramic materials, such as yttria stabilized zirconia ceramic materials.
Yttrium oxide is also used as a high brightness fluorescent powder for large screen televisions and other cathode ray tube coatings.
