Аннотация:The 950 degrees C isothermal section of the InPO4-Na3PO4-Li3PO4 ternary system was studied and constructed; one-, two, and three-phase fields are outlined. Five solid-solution regions exist in the system: solid solutions based on the complex phosphate LiNa5(PO4)(2) (olympite structure), the indium ion stabilized high-temperature Na3PO4 phase (Na3(1 - x)Inx(PO4); space group Fm (3) over bar m), the complex phosphate Na3In2(PO4)(3), and the a and-phases of the compound Li3In2(PO4)(3). A narrow region of melt was found in the vicinity of eutectic equilibria. All the phases detected in the system are derivatives of phases existing in the binary sub-systems. Isovalent substitution of lithium for sodium in Na3In2(PO4) (3) leads to a significant increase in the region of a NASICON-like solid solution.
