· Al12 N4 O12

Al₁₂N₄O₁₂ is an aluminum oxynitride ceramic combining aluminum nitride and alumina phases, belonging to the family of advanced structural ceramics with mixed covalent-ionic bonding. This material is primarily of research and specialized industrial interest for high-temperature applications where the combination of nitride and oxide phases offers enhanced thermal stability and mechanical performance compared to single-phase alternatives. It appears in niche applications requiring thermal shock resistance, wear protection, or electrical insulation at elevated temperatures, though it remains less common than conventional alumina or aluminum nitride in mainstream engineering.

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.
