Yttrium oxide Y₂O₃ is an important rare earth compound with unique heat resistance, corrosion resistance, high temperature stability, high dielectric constant and a series of excellent optical properties. It is widely used in advanced ceramics, optoelectronics, catalysts and efficient additives for functional composite materials.

In recent years, the rare earth industry has continued to develop, the application of rare earths has continued to deepen, and new materials technology has flourished. In particular, the application of rare earth oxides in new materials has become more and more extensive. As a result, the physical properties of oxide powders have become increasingly demanding, such as the requirements for specific surface area, particle size, and fluidity. The market demands are different for different powder particle sizes. In the past, small-particle rare earth oxides had special application fields. Today, large-particle rare earth oxides also have a certain market, and the market potential is huge.
