1. Disperse yttrium oxide powder into the alloy to prepare super heat-resistant alloy materials;

2. Ultrafine yttrium oxide powder can significantly improve the pixel quality of color TVs and the luminous efficiency of fluorescent lamps;

3. The research on yttrium oxide transparent ceramics is also very extensive, and yttrium oxide transparent ceramics are excellent materials for infrared transparent windows.

In addition, yttrium oxide is also widely used in fluorescent materials, catalyst materials, and waveguide materials.
