· JVASP-56743· Li4Ca3Si2N6

Li4Ca3Si2N6 is a lithium calcium silicon nitride ceramic compound belonging to the nitride ceramic family, a class of advanced ceramics valued for their high hardness and thermal stability. This material is primarily of research and development interest for solid-state battery electrolytes and other ionic conductor applications, where lithium-containing nitride ceramics show promise due to their potential for high ionic conductivity and structural stability. Compared to conventional oxide-based electrolytes, nitride ceramics offer advantages in chemical compatibility with lithium metal anodes and superior mechanical properties, though this particular composition remains largely in the exploratory phase of materials research.
