Aluminum fluoride powder is a high-purity white crystalline material known for its excellent chemical stability, low refractive index, and high thermal resistance. It plays a vital role in thin-film and plasma etching applications within the semiconductor industry.
Our aluminum fluoride powder is available with customizable particle sizes to meet a wide range of processing requirements. We also offer comprehensive after-sales support—please feel free to contact us if you have any questions.
Aluminum Smelting: As a fluxing agent in electrolytic aluminum production (Hall–Héroult process)
Optical Coatings: Low refractive index material used in antireflection and IR coatings
Ceramics & Glass: As a component to improve thermal resistance and lower melting point
Metallurgy: Flux for refining aluminum and other non-ferrous metals
Electronics & Semiconductors: Precursor in thin films and dry etching applications
Each batch of AlF₃ powder is provided with a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS). Third-party impurity analysis (ICP-MS, GDMS) and PSD reports can be provided upon request.
