Abstract

The phase relationships in the subsolidus region of the Li2MoO4–K2MoO4–MgMoO4–Sc2(MoO4)3–Lu2(MoO4)3 system have been studied by X-ray crystallography and vibrational spectroscopy. A phase of variable composition Li0.2K0.8–yMg1–xSc(Lu)1 + x(MoO4)3 (0 ≤ х ≤ 0.5; 0 ≤ y ≤ 0.3) with a NASICON structure (space group R\(\bar 3c\)) was synthesized by the ceramic route. The phase exhibits high conductivity, which makes it a candidate for use as a solid electrolyte with lithium and potassium ion conductivity. The unit cell parameters were determined, and IR and Raman spectra were interpreted.
