· JVASP-42378· Na2SnO2

Sodium stannate (Na₂SnO₂) is an inorganic ceramic compound composed of sodium and tin oxide, belonging to the family of stannate ceramics. It is primarily used in specialized applications including glass manufacturing as a polishing agent, ceramic coatings, and catalytic systems where tin oxide compounds provide thermal stability and chemical inertness. The material is notable for its role in precision optics production and as a precursor compound in advanced ceramics research, though it remains less common than alternative tin oxide formulations in mainstream engineering applications.
