Sodium chromite (NaCrO₂) is an inorganic ceramic compound belonging to the chromite family, consisting of sodium and chromium oxide phases. While primarily known as an intermediate compound in chromium metallurgy and chemical processing, it has attracted research interest for refractory applications and as a precursor material in specialized ceramic synthesis. Sodium chromite is not widely used in structural engineering applications compared to conventional ceramics, but its chromium-bearing composition makes it relevant in high-temperature chemistry, corrosion-resistant coatings, and materials research contexts where chromium oxide ceramics are explored.
