· Sr2SiO4

Sr₂SiO₄ is a strontium silicate ceramic compound belonging to the family of alkaline-earth silicates, which are typically employed in high-temperature and bioactive applications. This material is primarily investigated for biomedical uses—particularly as a bone graft substitute and in bioactive glass-ceramics—where its silicate structure promotes biocompatibility and apatite formation on the surface. It is also relevant to refractory and cement applications where strontium silicates provide thermal stability and chemical durability, making it an alternative to conventional calcium silicates in specialized high-temperature environments.
