Description
1. Product Overview
Europium Oxide Residue is a high-value rare earth intermediate derived from the downstream processing of europium-bearing materials. It serves as a critical feedstock for the recovery of high-purity Europium Oxide (Eu₂O₃), essential in red phosphors for displays, LEDs, and advanced defense optics. The product delivers a cost-efficient, traceable pathway to secure europium supply amid constrained primary mining output. Strategically, it enables manufacturers to de-risk rare earth sourcing while maintaining performance standards in luminescent and nuclear applications.
2. Key Specifications & Technical Characteristics
- Chemical Composition: Eu₂O₃-bearing residue with total rare earth oxides (TREO) 45–65%; major impurities include Gd₂O₃, Sm₂O₃, Fe₂O₃, CaO, SiO₂
- Purity/Grade: Europium content 8–15% Eu₂O₃ basis; industrial leaching grade
- Physical Characteristics: Fine powder form, reddish-brown to tan color, particle size D50 15–45 μm, bulk density 1.2–1.8 g/cm³
- Packaging Options: 25 kg UN-rated woven PP bags with PE liner, 1 MT jumbo bags, or 20 MT bulk in lined containers
- Shelf Life: Chemically stable; 24 months under dry, covered storage
3. Core Industrial Applications
- Primary Industries: Phosphor & LED manufacturing, specialty glass, nuclear control rods, rare earth separation/refining
- Specific Use Cases: Feedstock for solvent extraction to produce 4N–5N Eu₂O₃; dopant source for red phosphor formulations in CRT, PDP, and LED systems
- Performance vs Alternatives: Offers 30–40% lower input cost vs. virgin monazite-derived Eu₂O₃ while providing comparable downstream yield after refining
- Efficiency/Cost Advantages: Reduces raw material volatility, shortens separation cycles due to pre-concentrated Eu content, and lowers radioactive waste handling vs. primary ores
4. Competitive Advantages
- Quality Consistency: Batch-tested with ICP-OES/XRF certificates; ≤5% variation in Eu content per lot
- Supply Reliability: Long-term contracts available from audited separation facilities; 200 MT/month allocation capacity
- Logistics Capability: IAEA-compliant handling, global CFR/CIF shipping, dangerous goods certified partners
- Price Competitiveness: Indexed to Asian Metal with residue discount model; 15–25% below spot Eu₂O₃ equivalent
- Sustainability: Supports circular economy by recovering Eu from secondary streams; reduces mine dependency and tailings footprint
- Technical Support: Full SDS, REACH/ROHS docs, radioactivity reports, and toll-refining guidance provided
5. Commercial & Supply Information
- Minimum Order Quantity (MOQ): BULK 20MT
- Loading Capacity: 20 MT per 20ft FCL
