· 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.
