· JVASP-118639· NaAlO

Sodium aluminate (NaAlO₂) is an inorganic ceramic compound formed from sodium and aluminum oxides, commonly encountered as a byproduct or intermediate in alumina processing and alkali-activated cement chemistry. It serves primarily in construction materials, water treatment, and specialized refractory applications where its alkaline reactivity and bonding characteristics are leveraged; it is particularly valued in geopolymer and alkali-activated binder systems as an alternative to conventional Portland cement, offering potential for lower-carbon manufacturing. Engineers select this material class when seeking sustainable binding systems, high-temperature stability, or chemical durability in harsh environments, though real-world deployment typically involves sodium aluminate as a component within composite binders rather than as a monolithic ceramic.
