Super-fine K-doped Li2ZrO3 powders were synthesized via the citric acid-ethylene glycol complexing, with the nitrates of lithium, zirconyl and potassium as the materials. Then, the precursor of K-doped Li2ZrO3 and the K-doped Li2ZrO3 powders were characterized by means of TG-DSC, XRD and SEM. Moreover, the thermal decomposition of the gel and the formation of the tetragonal crystalline form were analyzed.
