Aluminium fluoride granules are high-purity, low-dust materials designed for efficient handling, precise dosing, and excellent thermal stability in various industrial and high-tech applications. Produced under controlled conditions, our AlF₃ granules typically achieve a purity of ≥99.9%, ensuring outstanding chemical consistency and minimal levels of impurities such as alkali and heavy metals.
Our AlF₃ granules are available in customized sizes according to application needs. We also offer comprehensive after-sales support—please feel free to contact us if you have any questions.
Aluminum Electrolysis: Used as a flux in Hall–Héroult cells to reduce the melting point of alumina and improve cell efficiency
Optical Coatings: Granular form simplifies dosing in vacuum evaporation and PVD coating systems
Metallurgy: Used as a fluxing and modifying agent for non-ferrous alloys
Glass and Ceramics: Component in specialized glasses and ceramic matrices for improved thermal and mechanical properties
Chemical Industry: Reactant in fluorination processes and catalyst synthesis
Each batch of AlF₃ granules is supplied with a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS). Additional testing (e.g., impurity profile, particle size distribution) is available upon request.
As a trusted aluminium fluoride supplier of high-purity specialty materials, we deliver consistent quality, advanced manufacturing, and low impurity content.
