Product Overview
UltraDry™ calcium fluoride (CaF₂) is a high-purity, anhydrous powder designed for demanding laboratory applications where moisture sensitivity and trace metal contamination are critical concerns. With a guaranteed 99.99% purity on a metals basis, this grade ensures minimal impurities, making it ideal for optical coatings, infrared spectroscopy, and advanced materials synthesis. The UltraDry™ designation indicates rigorous moisture control during packaging, preserving the material’s integrity for long-term storage and precise experimental reproducibility. The powder form allows for uniform dispersion in solvents or matrices, while its chemical stability under inert conditions enhances versatility in specialized workflows. Unlike conventional calcium fluoride, this grade undergoes additional purification steps to eliminate residual metals and oxides, ensuring consistent performance in high-sensitivity applications. Its low refractive index and broad transparency range (from UV to IR) further extend its utility in photonic and analytical research. Packaged in airtight, moisture-barrier containers, the product maintains its ultra-dry state until use, reducing the risk of hydration-induced degradation. Whether used as a substrate, dopant, or reagent, this calcium fluoride variant delivers reliability for experiments requiring exceptional purity and controlled environmental conditions.
FAQs
1. What is the difference between UltraDry™ and standard calcium fluoride?
UltraDry™ undergoes additional drying and packaging processes to minimize moisture content and metal impurities, unlike standard grades which may contain trace hydration or lower purity levels.
2. Can this be used for IR spectroscopy without further purification?
Yes, the 99.99% purity and anhydrous nature make it suitable for IR spectroscopy applications without requiring additional treatment, provided proper handling protocols are followed.
3. How should this product be stored to maintain its UltraDry™ properties?
Store in the original sealed container under inert gas (e.g., argon or nitrogen) and keep in a desiccator at room temperature to prevent moisture absorption.
4. Is this compatible with halogenated solvents for optical coating preparations?
The powder disperses well in non-polar solvents like chloroform or dichloromethane, but compatibility tests are recommended for specific formulations due to potential reactivity with certain halogens.
5. What alternatives exist for applications requiring lower purity calcium fluoride?
Standard reagent-grade calcium fluoride (97-99%) is available for general lab use, though it may contain higher moisture or metal impurities unsuitable for high-precision tasks.
