· JVASP-58340· CaAlSiO4F

Calcium aluminum silicate fluoride (CaAlSiO₄F) is a fluorine-containing silicate ceramic compound that combines calcium, aluminum, and silicon oxides with fluoride substitution. This material belongs to the family of advanced oxyfluoride ceramics, which are primarily investigated in research and development contexts for applications requiring enhanced thermal stability, chemical durability, and low thermal expansion. The fluoride incorporation can modify sintering behavior and mechanical properties compared to conventional calcium aluminosilicates, making it of interest for specialized refractory, optical, and composite applications where thermal shock resistance or specific thermal expansion matching is critical.
