· JVASP-50748· NaAl11O17

NaAl11O17 is a sodium aluminate ceramic compound belonging to the family of refractory alumina-based materials. This phase is primarily encountered in high-temperature ceramic systems and cement chemistry, where it forms as an intermediate or secondary phase rather than as a primary engineered material. It is notable in the context of calcium aluminate cements and refractory castables, where its presence and hydration behavior influence long-term durability and thermal stability; engineers working with these systems must account for its formation during processing and service to predict performance and prevent unwanted phase transitions.
