Yttrium oxide (Y2O3) is a white rare earth oxide that is insoluble in water and alkali, but soluble in acid. It is a typical C-type rare earth sesquioxide with a body-centered cubic structure. Yttrium oxide is often used as a functional additive material due to its high dielectric constant, good heat resistance, strong corrosion resistance, and a series of other excellent physical properties. It is widely used in the fields of atomic energy, aerospace, fluorescence, electronics, high-tech ceramics, etc. As a fluorescent powder matrix material, it is used in display, lighting, and marking fields; as a laser medium material, it is prepared into a transparent ceramic with high optical performance, which can be used as a laser working medium to achieve room temperature laser output;
As an up-conversion luminescent matrix material, it is applied in infrared detection, fluorescence labeling and other fields;
Made into transparent ceramics, it can be used for visible and infrared lenses, high-pressure gas discharge lamp tubes, ceramic scintillators, high-temperature furnace observation windows, etc.
Can be used as a reaction vessel, high temperature resistant material, refractory material, etc.;
As raw materials or additives, it is also widely used in high-temperature superconducting materials, laser crystal materials, structural ceramics, catalytic materials, dielectric ceramics, high-performance alloys and other fields.
