· Na4 Sr1 Si3 O9

Na₄Sr₁Si₃O₉ is a silicate ceramic compound combining sodium, strontium, and silicon oxides—belonging to the family of alkaline earth silicates used in specialized high-temperature and bioactive applications. This material is primarily of research and emerging industrial interest, particularly in bioceramics and glass-ceramic compositions where strontium incorporation offers potential benefits for bone bioactivity and radiopacity. Its alkaline character and silicate network structure make it a candidate for applications requiring controlled dissolution, biocompatibility, or thermal stability in niche engineering contexts.
