Product Overview
Lithium Fluoride (LiF) in PuratrOnic™ grade offers exceptional purity at 99.99% (metals basis), making it a critical material for advanced laboratory applications requiring minimal trace metal contamination. This crystalline powder is chemically inert, thermally stable, and highly transparent across a broad spectral range, from ultraviolet to infrared wavelengths. Its low refractive index and high damage threshold make it particularly suitable for optical coatings, laser systems, and spectroscopic analysis where precision and reliability are paramount. The PuratrOnic™ designation ensures rigorous quality control, with impurities reduced to parts-per-million levels, guaranteeing consistency in high-sensitivity experiments. The material’s hygroscopic nature necessitates careful handling and storage under dry conditions to maintain its integrity. Available in multiple pack sizes (250g, 50g, 10g), this grade is optimized for researchers and engineers demanding ultra-pure reagents for cutting-edge applications.
FAQs
1. What is the difference between PuratrOnic™ and standard-grade Lithium Fluoride?
PuratrOnic™ grade undergoes additional purification steps to achieve 99.99% metals basis purity, significantly reducing trace metal impurities compared to standard grades, which typically range between 98-99.5%. This makes it ideal for applications where even minor contamination can affect results.
2. Can this Lithium Fluoride be used for vacuum deposition processes?
Yes, the high purity and low moisture content of this PuratrOnic™ grade make it well-suited for physical vapor deposition (PVD) and other vacuum-based thin-film applications, ensuring uniform coatings with minimal defects.
3. How should I store Lithium Fluoride to prevent degradation?
Store in a tightly sealed container under inert gas (e.g., argon or nitrogen) in a cool, dry environment. Exposure to humidity can cause clumping or hydrolysis, compromising its optical and chemical properties.
4. Is this product compatible with common organic solvents?
Lithium Fluoride is generally insoluble in organic solvents but can react with strong acids. For cleaning or processing, use anhydrous conditions and avoid protic solvents like alcohols or water.
5. Are there alternatives to Lithium Fluoride for UV-transparent applications?
Magnesium Fluoride (MgF₂) is a common alternative for UV optics, offering similar transparency but with a slightly higher refractive index. However, LiF remains superior for applications requiring lower dispersion and broader spectral range coverage.
