Abstract—New methods for the synthesis of NASICON of the composition Na_{1 +} _xZr₂P_{3 –} _xSi_xO₁₂ (0 ≤ x ≤ 3) were presented. In the work, the method of pyrolysis of organic solutions was used, which takes a minimum time to synthesize the material. Various options for the composition and heat treatment of precursors were considered. The effect of rosin on the pyrolysis process and the phase composition of the final products was discussed. The optimal conditions for the synthesis of the low-dimensional monoclinic polymorph Na₃Zr₂Si₂PO₁₂ with homogeneous composition were determined.
