· Li4 Hf2 O6

Li₄Hf₂O₆ is a lithium hafnium oxide ceramic compound belonging to the family of mixed-metal oxides with potential electrochemical and structural applications. This material is primarily of research interest rather than established in high-volume industrial use, with investigations focused on its ionic conductivity and thermal stability as a candidate for solid-state electrolytes, thermal barriers, and refractory applications where hafnium's high melting point and lithium's ionic mobility can be leveraged.
