Calcium aluminate (CaAlO₂) is an inorganic ceramic compound commonly encountered as a constituent phase in calcium aluminate cements and refractory materials. It serves primarily as a binder and structural phase in high-temperature applications where chemical stability and thermal resistance are critical, particularly in cement formulations designed for rapid setting, chemical attack resistance, or elevated-temperature service. Engineers select calcium aluminate-based systems over conventional Portland cement when superior performance at extreme temperatures, aggressive chemical environments, or accelerated early strength development is required.
