Product Overview
Erbium(III) oxide (Er₂O₃), offered in REacton™ grade with 99.99% purity (REO basis), is a high-performance rare earth oxide engineered for demanding applications requiring exceptional optical and thermal properties. This ultra-fine white powder exhibits outstanding chemical stability, making it a preferred choice for advanced material formulations where trace impurities can compromise performance. The REacton™ designation ensures rigorous quality control, with particle size distribution optimized for uniform dispersion in matrices like glass, ceramics, and polymer composites. Its high refractive index and luminescent properties stem from the erbium ion’s unique 4f electron configuration, enabling precise doping in optical fibers and laser crystals. The material’s hygroscopic nature necessitates careful handling, though its thermal stability up to 2300°C makes it suitable for high-temperature processes like plasma spraying and ceramic sintering. Unlike lower-grade alternatives, this 99.99% pure variant minimizes batch-to-batch variability, critical for reproducible results in R&D environments. The powder’s surface area and morphology are tailored to enhance reactivity without compromising flow characteristics, ensuring consistent performance in both wet and dry processing methods.
FAQs
1. What is the difference between 99.99% and 99.9% Erbium(III) oxide?
The 99.99% grade contains 10x fewer impurities, particularly critical for applications where trace elements like iron, silicon, or calcium could interfere with optical properties or doping efficiency. The higher purity also reduces unwanted absorption bands in spectroscopic applications.
2. Can this Erbium(III) oxide be used directly for fiber optic doping?
While it meets purity requirements, additional processing like solution preparation or vapor deposition is typically required to incorporate it into fiber preforms. The powder’s fine particle size aids in creating homogeneous doping solutions.
3. How does the REacton™ grade compare to standard reagent grades?
REacton™ undergoes additional purification steps to remove metallic and anionic contaminants, with stricter controls on particle size distribution. This results in more consistent performance in sensitive applications like phosphor synthesis or thin-film deposition.
4. What precautions should be taken during storage?
Store in a desiccator or sealed container with moisture absorbers, as the material is mildly hygroscopic. Exposure to humid air can lead to surface hydrolysis, affecting its reactivity in subsequent processes.
5. Is this product compatible with standard ceramic processing techniques?
Yes, it integrates well with conventional methods like tape casting, slip casting, and uniaxial pressing. Its fine particle size promotes sintering at lower temperatures compared to coarser grades, though exact parameters depend on the specific ceramic matrix.
