Abstract: A lithium lanthanum zirconium oxide (LLZO) having a garnet crystal structure contains fluorine in an amount up to 40 mol %. The fluorine, which may be in the form of a lithium compound such as lithium fluoride, may act as a sintering aid and promote formation of the cubic garnet phase. The sintered oxide may be a dense ceramic that includes a plurality of distributed closed pores. Solid electrolyte membranes comprising the oxide can have an ionic conductivity of at least 1×10−4 S/cm.
