Ca3Al2O6

Ca3Al2O6 is a calcium aluminate ceramic compound, specifically a tricalcium aluminate phase commonly found in Portland cement clinker and high-alumina refractory systems. It is primarily valued in infrastructure and industrial high-temperature applications where chemical durability, rapid early strength development, and thermal stability are required, though it is rarely used as a pure standalone phase—instead functioning as a key constituent in cement and refractory blends that engineers tailor for specific performance demands.
