· Ba2 Na4 Si4 O12

Ba₂Na₄Si₄O₁₂ is an alkaline earth silicate ceramic belonging to the family of sodium barium silicates, which are synthetic compounds engineered for specific optical, thermal, and chemical properties. This material is primarily of research and specialized industrial interest, used in applications requiring materials with controlled porosity, ion-exchange capabilities, or specific refractive characteristics, such as in advanced ceramics, ion-exchange media, and experimental optical coatings. Its notable advantage over traditional silicates is the incorporation of both alkaline earth (barium) and alkali (sodium) cations, which can be tuned to achieve tailored thermal stability, chemical durability, and functional properties for niche applications.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
