Product Overview
Yttrium(III) oxide (Y₂O₃) with 99.99% purity (trace metal basis) is a high-performance rare earth oxide known for its exceptional thermal stability and optical properties. This ultra-pure white powder is synthesized under stringent quality controls to ensure minimal metallic impurities, making it ideal for demanding applications. The material exhibits excellent chemical resistance and maintains structural integrity at elevated temperatures, up to 2325°C. Its unique electronic configuration enables superior luminescence properties when doped with other rare earth elements, while the fine particle size distribution ensures uniform dispersion in composite materials. The oxide’s high refractive index and transparency in the infrared spectrum further enhance its functionality in specialized optical systems. Manufactured through advanced precipitation techniques, this grade meets rigorous analytical standards for trace metal content, with residual impurities strictly controlled below 100 ppm. The product is packaged in airtight containers to prevent moisture absorption, preserving its reactive surface characteristics.
FAQs
1. What is the typical particle size range for this Yttrium(III) oxide?
The material generally exhibits a particle size distribution between 1-5 microns, though this can vary slightly between production batches. For applications requiring specific particle sizes, we recommend contacting our technical team for current batch specifications.
2. How does the 99.99% trace metal basis specification differ from standard purity grades?
This specification indicates that all metallic impurities combined do not exceed 0.01% (100 ppm), with each individual metal impurity typically below 10 ppm. Standard purity grades often allow higher impurity levels and may not provide detailed trace metal analysis.
3. What precautions should be taken when handling this powder?
While generally stable, the fine powder can cause respiratory irritation. Always handle in a fume hood or with proper ventilation, wearing gloves and a dust mask. Avoid generating dust clouds and store in tightly sealed containers.
4. Can this material be used in vacuum environments?
Yes, Yttrium(III) oxide maintains its stability in vacuum conditions up to 10⁻⁶ torr. However, prolonged exposure to ultra-high vacuum may require pre-treatment to remove adsorbed gases from the surface.
5. What analytical techniques are used to verify the 99.99% purity?
The purity is confirmed through inductively coupled plasma mass spectrometry (ICP-MS) for trace metal analysis, complemented by X-ray diffraction (XRD) for phase purity and thermogravimetric analysis (TGA) for thermal stability verification.
