· JVASP-57845· Na2ZnSi2O6

Sodium zinc silicate (Na₂ZnSi₂O₆) is a silicate ceramic compound that combines alkali metal, transition metal, and silicate chemistry. This material is primarily encountered in research contexts for glass-ceramic systems, refractory applications, and functional ceramics, where the zinc incorporation provides enhanced thermal stability and chemical durability compared to pure sodium silicates. It is notable for potential use in bioactive ceramics, thermal insulation, and high-temperature sealing applications where its silicate backbone offers corrosion resistance.
