Product Overview
Lanthanum(III) fluoride anhydrous from the REactOn™ series delivers 99.9% purity (measured as rare earth oxides) for demanding laboratory and industrial applications. This high-purity compound is synthesized through controlled fluorination processes to ensure minimal moisture content and trace metal impurities. The anhydrous form eliminates hydration-related inconsistencies, making it particularly suitable for applications requiring precise stoichiometry. Its fine powder consistency (typically 1-5 micron particle size) ensures uniform dispersion in ceramic matrices or thin-film deposition processes. The material exhibits exceptional thermal stability up to 1400°C and maintains its structural integrity under reducing atmospheres. Optical-grade transparency in the UV-visible spectrum makes it valuable for specialty glass formulations. The REactOn™ certification guarantees batch-to-batch consistency with maximum 100ppm total rare earth impurities (excluding La) and <50ppm non-rare earth metallic contaminants. Packaged under argon atmosphere to prevent oxidation during storage.
FAQs
1. What is the difference between REactOn™ grade and standard lanthanum fluoride?
The REactOn™ grade undergoes additional purification steps to achieve 99.9% REO purity compared to standard grades that typically range between 99.0-99.5%. It also has stricter controls on particle size distribution and moisture content below 50ppm.
2. Can this product be used in hydrogen fluoride generation?
While lanthanum fluoride can theoretically serve as a fluorine source, this anhydrous grade is optimized for solid-state applications rather than gas generation. The high purity makes it more suitable for ceramic additives than chemical synthesis.
3. What precautions should be taken when handling this powder?
Use in a fume hood with proper PPE including nitrile gloves and dust mask. The fine particle size makes it particularly prone to inhalation hazards. Store opened containers with desiccant to prevent moisture absorption.
4. How does the particle size affect performance in optical applications?
Smaller particle sizes (1-5 microns) reduce light scattering in transparent matrices. This grade’s controlled particle distribution helps maintain optical clarity in glass and ceramic composites while minimizing defects.
5. What documentation is provided with each batch?
Every shipment includes a certificate of analysis detailing actual purity levels, particle size distribution, moisture content, and trace elemental analysis via ICP-MS. Additional safety data sheets are available upon request.
