· JVASP-50445· Li4ZrO4

Li₄ZrO₄ is an inorganic oxide ceramic compound containing lithium and zirconium, representing a mixed-metal oxide in the lithium-zirconate family. This material is primarily investigated in research contexts for solid-state battery applications and advanced ceramic systems where lithium-ion conductivity and thermal stability are desired. While not yet established as a commodity engineering material, lithium zirconate compounds are notable for their potential in electrolyte materials, thermal barrier coatings, and high-temperature ceramic matrices where chemical inertness and ionic transport properties become critical.
