Product Overview
Europium(III) oxide from REacton™ delivers unmatched purity at 99.996% (REO), making it the gold standard for applications demanding ultra-low trace metal contamination. This fine, white powder exhibits exceptional thermal stability and luminescent properties, critical for advanced optical materials and high-performance phosphors. The REacton™ grade ensures batch-to-batch consistency with minimal non-rare-earth impurities (<10 ppm typical), eliminating background interference in sensitive analyses. Its high surface area and uniform particle distribution enhance reactivity in solid-state synthesis while maintaining excellent flow characteristics for precise dispensing. The material’s hygroscopic nature is carefully controlled during packaging to preserve its pristine state, with each lot accompanied by comprehensive ICP-OES certification. Unlike lower-grade alternatives, this europium oxide undergoes proprietary purification to remove residual fluorides and chlorides, ensuring compatibility with halogen-sensitive processes. The powder’s density (7.42 g/cm³) and refractive index (1.93) are optimized for optical applications, while its cubic crystal structure provides isotropic properties essential for specialized ceramics. Whether used as a dopant, precursor, or standalone material, this product meets the exacting standards of research laboratories and industrial R&D facilities requiring absolute reliability in rare earth oxides.
FAQs
1. What is the typical particle size distribution for this Europium(III) oxide?
The powder features a controlled particle size range of 1-5 microns with D50 typically at 2.8 microns, optimized for homogeneous mixing in composite materials and consistent reaction kinetics.
2. How does the REacton™ grade differ from standard 99.9% europium oxide?
REacton™ grade achieves 99.996% purity with <10 ppm total non-rare-earth impurities versus 100+ ppm in standard grades, plus stricter control over anion content (F⁻ <50 ppm, Cl⁻ <30 ppm) and particle morphology.
3. What packaging materials are used to prevent moisture absorption?
Each pack is sealed in a triple-layer barrier pouch with silica gel desiccant, then vacuum-sealed in an aluminum-laminated outer bag to maintain <0.1% moisture content during storage.
4. Can this oxide be used directly for thin-film deposition methods?
Yes, the powder’s high purity and consistent morphology make it suitable for PVD, CVD, and sol-gel processes, though additional milling may be required for specific deposition techniques.
5. What analytical techniques are used for quality certification?
Certification includes ICP-OES for elemental purity, XRD for phase confirmation, BET for surface area, and Karl Fischer titration for moisture content, with all data provided in the COA.
