· Ba1 Al2 Si2 O8

Ba₁Al₂Si₂O₈ is an aluminosilicate ceramic compound belonging to the feldspar family, specifically a barium aluminosilicate. This material is encountered primarily in specialized ceramic applications where thermal stability, electrical insulation, and chemical durability are required, such as in refractory compositions, electrical porcelains, and glass-ceramic systems. It is valued for its ability to maintain structural integrity at elevated temperatures and resist chemical attack, making it an alternative to more common feldspathic ceramics when barium-bearing phases offer processing or performance advantages in engineered ceramic matrices.

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.
