· JVASP-35164· Li4Ca2MgSi2N6

Li4Ca2MgSi2N6 is a lithium-calcium magnesium silicate nitride ceramic compound belonging to the oxynitride/nitride ceramic family. This is a research-phase material primarily investigated for advanced structural and functional applications where lightweight, high-stiffness ceramics with thermal stability are needed. The combination of lithium, alkaline-earth, and transition elements in a nitride matrix suggests potential for applications requiring both mechanical performance and ionic conductivity or thermal properties that distinguish it from conventional alumina or silicon nitride ceramics.
