Abstract
NASICON with a composition of Na3Zr2Si2PO12 was first synthesized by pyrolysis of a mixture of organic solutions. The ratio of initial components required for the formation of this composition was determined. The temperature conditions for processing the precursor were examined. The material was obtained with an average grain size of 0.2 μm. The composition and morphology of the compound were confirmed by X-ray diffraction analysis and scanning electron microscopy. The synthesis of NASICON takes 9 h on the average, which is the minimum time among all known methods for the preparation of this material.
