Calcium aluminate (CaAl₂O₄) is an advanced ceramic compound belonging to the aluminate family, commonly encountered as a phase in calcium aluminate cements and refractory materials. It is primarily used in high-temperature applications where chemical stability and thermal resistance are critical, including refractory linings for industrial furnaces, cement chemistry, and specialized casting applications. Engineers select this material for its ability to maintain structural integrity at elevated temperatures and its resistance to slag and corrosive molten materials, making it preferred over standard Portland cement in chemically aggressive environments.
