Phase formation in the systems Ag 2MoO 4-MMoO 4-Al 2(MoO 4) 3, M - Zn, Cd, Ca

The phase formation in the field of subsolidus Ag 2MoO 4-MMoO 4-Al 2(MoO 4) 3, M - Zn, Cd, Ca has been studied by the XRD method. Within the system Ag 2MoO 4-ZnMoO 4-Al 2(MoO 4) 3 the formation of compound AgZn 3Al(MoO 4) 5 and of variable composition phase Ag 1-xZn 1-xAl 1+ x(MoO 4) 3 has been determined. The triple molybdate AgZn 3Al(MoO 4) 5 crystallizes in the triclinic system (sp. gr. pī, Z = 2). Ag 1-xZn 1-xAl 1+ x(MoO 4) 3, it refers to the structural type NASICON (sp. gr. R 3c, Z = 6).
