BaSi4O9
ceramic· JVASP-45378· BaSi4O9
Barium silicate (BaSi₄O₉) is an inorganic ceramic compound belonging to the silicate family, composed of barium oxide and silicon dioxide in a fixed stoichiometric ratio. This material is primarily investigated for applications requiring high-temperature stability and chemical inertness, particularly in specialized glass and ceramic coatings, refractory formulations, and as a precursor in advanced ceramic processing. Barium silicates are notable for their thermal shock resistance and low thermal expansion characteristics, making them attractive alternatives to conventional silicates in applications where thermal cycling or corrosive environments present challenges.

Regulatory Screening
Environmental
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.
