· JVASP-88635· CaAl2SiO6

CaAl₂SiO₆ is an anorthite-based ceramic compound belonging to the plagioclase feldspar family, notable for its high-temperature stability and low thermal expansion characteristics. This material is primarily encountered in refractories for furnace linings, ceramic glazes, and high-temperature structural applications where thermal shock resistance and chemical inertness are critical; it also appears in research contexts exploring advanced ceramic composites and refractory matrices where its stable crystal structure and melting behavior offer advantages over conventional silicate ceramics.
