· JVASP-11401· Sr3AlO4F

Sr3AlO4F is a strontium aluminate fluoride ceramic compound belonging to the family of mixed-anion ceramics that combine oxides and fluorides. This material is primarily investigated in research contexts for optical and thermal applications where the fluoride component can modify both the crystal structure and functional properties compared to purely oxide-based alternatives. Industrial interest focuses on solid-state lighting phosphors, thermal barrier coatings, and specialized refractories where the strontium aluminate base combined with fluoride substitution offers potential advantages in photoluminescence efficiency, phase stability, or wear resistance.
