“…The main complication of these compounds is complex polymorphism that makes it difficult to obtain NASICON‐like ceramics of high phase homogeneity and with good working characteristics 5 . Thus, investigation of ionic conductivity, cation mobility, and improvements to the phase stability of complex phosphates with NASICON and NASICON‐like structures is of interest today 6–8 …”

Phase equilibrium in ternary system Li3PO4–Na3PO4–InPO4 and formation of heterovalent Zr‐substituted solid solutions (up to 15 mol%) for In3+ in Li3In2(PO4)3 and Na3In2(PO4)3 complex phosphates were studied by the cross‐section method at 950°C. Samples obtained were investigated by X‐ray powder diffraction and impedance spectroscopy. Ionic conductivity of Na3In2(PO4)3 and Li3In2(PO4)3 complex phosphates is about 10−2 S/cm at 300°C. Heterovalent substitution was performed according to the scheme: In3+=Zr4++v, where v is a vacancy in cationic sublattice. Zr‐substituted (15 mol%) Na3In2(PO4)3 and Li3In2(PO4)3 have ionic conductivity of about 10−1 S/cm at 300°C.
