Sodium Aluminum Fluoride (Na₃AlF₆), commonly known as Cryolite, is a fluoride-based material used primarily in the aluminum smelting industry, as well as in various thin-film deposition processes. Na₃AlF₆ pellets are utilized in the production of thin films through evaporation techniques, particularly in optical coatings and specialized applications that require fluoride-based compounds.

Key Applications:

• Optical Coatings: Na₃AlF₆ is used in the deposition of anti-reflective (AR) coatings on optical components due to its transparency in the ultraviolet (UV) to infrared (IR) wavelength range.
• Aluminum Production: Cryolite is essential in the electrolytic reduction of aluminum in the Hall-Héroult process, although this is outside its primary thin-film deposition role.
• Surface Passivation: Thin films of Na₃AlF₆ can be used for surface passivation layers in semiconductors and other electronics.
• Fluoride-based Thin Films: It is used in the deposition of fluoride-based films for optics and electronics, especially in UV-sensitive applications where high transparency is needed.

Features:

• High UV Transparency: Na₃AlF₆ is transparent in the UV and IR spectral regions, making it suitable for optical coatings in UV-sensitive applications.
• Good Adhesion: Forms thin films with excellent adhesion to a variety of substrates.
• Low Refractive Index: Offers a low refractive index, which is beneficial for anti-reflective coatings and optical interference filters.
• Corrosion Resistance: Provides a protective layer with good resistance to chemical and environmental factors.
