Phase formation in the system involving silver, zinc and chromium molybdates

Phase formation in the Ag 2MoO 4-ZnMoO 4-Cr 2(MoO 4) 3 system was studied by the X-ray phase analysis in the subsolidus region. The formation of compound AgZn 3Cr(MoO 4) 5 and the variable-composition Ag 1. xZn 1. xCr 1+x(MoO 4) 3 phase was determined. The ternary molybdate AgZn 3Cr(MoO 4) 5 crystallizes in triclinic system (sp. gr. P1, Z=2). Ag 1-xZn 1-xCr 1+x(MoO 4) 3 is related to the NASICON (sp. gr. R 3c, Z=6).
