· JVASP-100369· Na4SrCaSi2

Na₄SrCaSi₂ is a complex silicate ceramic compound containing sodium, strontium, and calcium—a material class primarily investigated in research contexts rather than established industrial production. This composition belongs to the family of alkaline-earth silicates, which are explored for applications requiring lightweight ceramics with moderate stiffness and specific thermal or chemical properties. The material's potential lies in specialty applications where the combination of these elements offers advantages in biocompatibility, thermal stability, or ion-exchange behavior compared to conventional silicates.
