· JVASP-58320· NaAlSi2O6

NaAlSi₂O₆ is an aluminosilicate ceramic compound belonging to the feldspathoid mineral family, characterized by its framework silicate structure containing sodium, aluminum, and silicon oxide components. This material appears in commercial ceramics, refractories, and glass-ceramic applications where its thermal stability and chemical durability are leveraged; it also serves as a raw material or precursor in advanced ceramic processing and sintering of technical ceramics. Compared to pure silica or alumina ceramics, sodium aluminosilicates offer intermediate thermal expansion coefficients and improved glass-forming characteristics, making them valuable in low-expansion glass-ceramics and high-temperature composite matrices.
