· JVASP-55320· CaFeSi2O6

CaFeSi2O6 is a calcium iron silicate ceramic compound belonging to the pyroxene mineral family, characterized by a silicate crystal structure with divalent iron and calcium cations. This material is primarily encountered in geological contexts and high-temperature ceramic applications, where its thermal stability and silicate-based structure make it relevant for refractory systems, slag management in metallurgy, and experimental studies of iron-bearing ceramics. Engineers consider this compound when designing high-temperature environments or studying mineral-phase equilibria in complex oxide systems where iron-calcium-silicate interactions are critical.
