· Ba3 Si6 N4 O9

Ba₃Si₆N₄O₉ is an oxynitride ceramic compound combining barium, silicon, nitrogen, and oxygen phases. This material belongs to the family of advanced ceramics that leverage oxynitride bonding to achieve tailored combinations of mechanical strength, thermal stability, and chemical durability beyond traditional silicate or nitride ceramics alone. While primarily found in research and specialized industrial settings rather than commodity applications, oxynitride ceramics like this composition are explored for high-temperature structural applications and harsh chemical environments where conventional refractories or engineering ceramics show limitations.

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.
