The Effect of Ball Milling Time on the Synthesis of Garnet-like Li7La3Zr2O12 Li-ion Conductor

In this study Li7La3Zr2O12 Li-ion conductor was synthesized by applying a mechanical activation followed by heat treatment to a mixture of lithium carbonate (Li2CO3), lanthanium oxide (La2O3) and zirconium oxide (ZrO2). The effect of different milling times during synthesis on the formation of crystal structure phases, morphological properties and particle size were investigated by X-ray diffraction (XRD) pattern and scanning electron microscope (SEM). Detailed crystal structure analysis done by MAUD software demonstrated while first milling time is effective on synthesis of the high ionic conductive phase of the Li7La3Zr2O12 cyrstal last milling time is effective on the cyrstallite size
