· JVASP-57532· Na4SrSi3O9

Na4SrSi3O9 is a silicate ceramic compound combining sodium, strontium, and silicon oxides, belonging to the family of alkaline-earth silicates used in specialized ceramic applications. This material is primarily investigated in research contexts for optical, thermal, and refractory applications where its strontium content provides thermal stability and chemical durability. Its selection over standard silicates is driven by requirements for enhanced thermal properties, lower thermal expansion, or specific luminescent behavior in high-temperature or chemically demanding environments.
