· Na4 Ca6 Si6 O20

Na₄Ca₆Si₆O₂₀ is a calcium silicate ceramic compound belonging to the family of alkali-containing silicates, with potential applications in bioceramics and solid-state chemistry. This composition represents a mixed-cation silicate phase that may be encountered in clinker chemistry, cement systems, or experimental bioactive ceramic development, though it is not a widely commercialized engineering material. Engineers would consider this material primarily in research contexts exploring biocompatibility, ion-release behavior for bone regeneration, or as a constituent phase in specialized cement formulations.
