Description of Yttrium oxide Powder
Yttrium Oxide (Y₂O₃) powder is a high-purity, white, crystalline rare-earth oxide known for its thermal stability, infrared and optical transparency, and excellent dielectric properties. As a key advanced ceramic material, Y₂O₃ is widely used in phosphors for LEDs and color television tubes, as a stabilizer in zirconia-based ceramics (YSZ), and in the fabrication of yttrium iron garnets (YIG) for microwave and RF filters. Additionally, Yttrium Oxide granules and powders are critical in producing high-performance technical ceramics, thermal barrier coatings, and specialty glass, thanks to their high melting point (~2410°C), chemical inertness, and low thermal expansion coefficient.
