Abstract
A process of synthesizing a lithium lanthanum zirconium oxide (LLZO) powder may include mixing a lithium salt, water, and a precursor blend comprising a lanthanum precursor and a zirconium precursor to form a mixture. The process may include heating the mixture at low pressure to form a dried lithiated powder. The process may include calcining the dried lithiated powder to form a lithium lanthanum zirconium oxide powder. The LLZO powder may include a cubic garnet phase purity of greater than 95 wt %.
