· Sr12 Si4 O20

Sr12Si4O20 is an apatite-based silicate ceramic compound containing strontium, silicon, and oxygen in a structured crystal lattice. This material is primarily investigated in biomedical research contexts for bone regeneration and tissue engineering applications, where strontium's bioactive properties promote osteogenic response alongside the established biocompatibility of silicate ceramics. Compared to conventional hydroxyapatite, strontium-substituted silicates offer enhanced biological activity and potential for controlled ion release, making them candidates for advanced orthopedic and dental scaffolds, though deployment remains largely limited to research and development rather than established clinical practice.
