Product Overview
Lanthanum(III) fluoride, anhydrous, REactOn™ grade, is a high-purity (99.99% REO) rare earth compound designed for demanding laboratory and industrial applications. This fine, white crystalline powder exhibits exceptional thermal stability, low refractive index, and resistance to moisture absorption, making it a preferred choice for advanced material synthesis. Its ultra-low impurity profile ensures consistency in optical coatings, where even trace contaminants can compromise performance. In glass manufacturing, it acts as a fluxing agent, improving melt fluidity and enhancing transparency in specialty glasses. The REactOn™ certification guarantees stringent quality control, with batch-to-batch uniformity verified through ICP-OES and XRD analysis. The anhydrous form eliminates hydration-related variability, critical for reproducible results in high-temperature processes. Packaged under inert conditions to prevent oxidation, this product maintains its purity during storage and handling. Its compatibility with fluoride-based systems and resistance to thermal shock further expand its utility in ceramic formulations and laser crystal production.
FAQs
1. What is the particle size distribution of this lanthanum fluoride powder?
The typical particle size ranges between 1-5 microns with a narrow distribution, optimized for uniform dispersion in both aqueous and organic media. The powder undergoes jet milling to minimize agglomeration while maintaining flowability.
2. How does the REactOn™ grade differ from standard laboratory grades?
REactOn™ grade undergoes additional purification steps, including zone refining and vacuum distillation, to achieve 99.99% REO purity with <10 ppm total metallic impurities. Standard grades typically contain 99.9% purity with higher trace element levels that may interfere with sensitive applications.
3. Can this product be used directly in fluoride glass melting without further treatment?
Yes, the anhydrous form is pre-dried to <0.01% moisture content and requires no additional drying before use in glass melting. Its low hydroxyl content prevents bubble formation in the final glass product, which is critical for optical-grade materials.
4. What precautions should be taken when storing this compound long-term?
Store in the original sealed container with desiccant packs at 15-25°C, away from direct sunlight and moisture. The container features a dual-seal closure system to maintain inert conditions. Avoid storage near ammonia or alkaline materials, as these can react with fluoride ions over time.
5. Is this lanthanum fluoride compatible with platinum crucibles during high-temperature processing?
While generally compatible, prolonged contact above 1200°C may cause minor corrosion due to fluoride ion mobility. For extended processing, we recommend using high-purity graphite or zirconia-coated crucibles to prevent contamination of your final product.
