· JVASP-137289· YAl2N3

YAl2N3 is a ternary nitride ceramic compound combining yttrium, aluminum, and nitrogen, belonging to the family of rare-earth aluminum nitrides. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in high-temperature structural ceramics and advanced refractory systems where thermal stability and hardness are critical. The yttrium-aluminum nitride family is explored for its potential to combine the thermal shock resistance of aluminum nitride with the high-temperature oxidation resistance benefits of rare-earth dopants, making it a candidate for next-generation aerospace and thermal management applications where conventional ceramics approach their limits.

Export Control

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.
