Yttrium Oxide (Y2O3): A Versatile Rare Earth Material for Industrial & Scientific Excellence
Yttrium oxide (Y2O3), also known as yttria, is a critical rare earth oxide with unparalleled versatility across industries. With CAS Number 1314-36-9, this inorganic compound combines exceptional chemical stability and high-temperature resilience, making it indispensable in modern technology.
As an authorized supplier under China Rare Earth Group, Ruisen delivers high-purity Y2O3 tailored for advanced applications, from ceramic laser systems to solid oxide fuel cells.
Premium Yttrium Oxide (Y₂O₃): Key Features & Technical Specifications
Ruisen’s yttrium oxide powder meets rigorous standards, available in purity grades ranging from 99.99% to 99.999% (trace metals basis). Key properties include:
Property | Specification |
---|---|
Linear Formula | Y₂O₃ |
Purity | 99.99% – 99.999% |
Particle Size | 50 nm – 5 µm (customizable) |
Melting Point | 2,410°C |
Density | 5.01 g/cm³ |
Chemical Stability | Resistant to aqueous solution, acids |
The linear formula Y₂O₃ ensures consistency, supported by a certificate of analysis for every batch. Its refractory nature and low-energy synthesis processes align with sustainable manufacturing.
Yttrium Oxide vs. Alternatives: Superior Performance in Demanding Applications
While materials like alumina or zirconia are common substitutes, Y₂O₃ outperforms in critical metrics:
Property | Y₂O₃ | Alumina | Zirconia |
---|---|---|---|
Thermal Stability | Up to 2,410°C | 2,072°C | 2,715°C |
Dielectric Strength | High | Moderate | Moderate |
Optical Clarity | Exceptional | Low | Medium |
For instance, yttria stabilized zirconia (YSZ) relies on Y₂O₃ to stabilize the zirconium lattice, enhancing durability in high-temperature applications like fuel cells.
