Аннотация:The 950A degrees C isothermal section of the ScPO4-Na3PO4-Li3PO4 three-component system was plotted and studied; one-, two-, and three-phase fields were bounded. Three solid solution fields exist in the title system: one based on LiNa5(PO4)(2) complex phosphate (olympite structure), another on scandium-stabilized high-temperature Na3PO4 phase Na3(1 - x)Sc (x/3)a-(2/3x) PO4 (space group Fm3m), and the third on Na3Sc2(PO4)(3) (NASICON structure). All phases found in the title system are derivatives of phases that exist in its subsystems. Lithium-for-sodium isovalent substitutions in Na3Sc2(PO4)(3) considerably increase the NASICON-type solid solution field but negatively influence the conductivity of the phase.
