The subsolidus region of the Ag2MoO4-CoMoO4-Al-2(MoO4)(3) ternary salt system was studied by X-ray powder diffraction analysis. New compounds Ag1-x Co1-x Al1 + x (MoO4)(3) (0 a parts per thousand currency sign x a parts per thousand currency sign 0.4) and AgCo3Al(MoO4)(5) were detected to form. The variable-composition phase Ag1-x Co1-x Al1 + x (MoO4)(3) is of the NASICON structure type (space group ). AgCo3Al(MoO4)(5) crystallizes in the triclinic symmetry (space group Z = 2) with the unit cell parameters a = 6.9101(6), b = 17.519(1), c = 6.8241(6) , alpha = 87.356(7)A degrees, beta = 101.078(7)A degrees, and gamma = 91.985(9)A degrees. The compounds are thermally stable until 770-780 and 760A degrees C, respectively.
