Ca2Al2SiO7

Ca2Al2SiO7 is a calcium aluminosilicate ceramic compound belonging to the anorthite-based family of materials, commonly encountered as a phase in cement chemistry and refractory compositions. This material appears primarily in high-temperature applications where thermal stability and chemical resistance are critical, including Portland cement clinker phases, aluminosilicate refractories, and specialized binders for extreme-temperature environments. Engineers select calcium aluminosilicates for their ability to maintain structural integrity at elevated temperatures and resist corrosion in harsh chemical or thermal cycling conditions, making them valuable alternatives to pure oxides when intermediate thermal expansion and sintering behavior are advantageous.
