AlF3

Notas

Aluminium fluoride (AlF3) is an inorganic compound that exists as a colorless solid in both its anhydrous state and as various hydrates. While primarily utilized industrially in the primary production of aluminium metal, its role within specialized ceramic or glass chemistry is centered on its function as a fluorinated additive. In glaze or glass systems, fluorine-bearing compounds often act as potent fluxing agents, capable of lowering the overall melting temperature and reducing the viscosity of the melt. Due to the high volatility of fluorine at elevated temperatures, AlF3 can influence the surface characteristics and development of crystalline phases within a cooling glaze matrix, potentially contributing to opacification or specific surface textures. Careful management of kiln atmospheres is required when incorporating fluoride-based materials, as they can volatilize and impact kiln furniture or glaze finish.
