· JVASP-52816· Nd3Al3Si3N2O12

Nd3Al3Si3N2O12 is an oxyntride ceramic compound combining rare-earth (neodymium), aluminum, silicon, nitrogen, and oxygen elements into a single-phase material. This is a research-stage compound studied for its potential in high-temperature structural applications, where the combination of nitrogen and oxygen in the lattice can provide improved thermal stability and mechanical properties compared to conventional oxide or nitride ceramics alone.
