FORMATION OF SOLID SOLUTIONS WITH PYROCHLORE-TYPE STRUCTURE IN THE SYSTEM K2CO3-AgNO3-Sb2O3-MoO3 ON HEATING
Phase formation features of solid solutions in the system хAgNO3-(y-х)K2CO3-ySb2O3-2(2-y)МоO3 (0. x. y, 1,0. y. 2,0) on heating have been investigated. For the temperature 1023 K in the concentration triangles KSbO3-MoO3-AgSbO3 specified existence area of complex antimony (V) oxides, containing potassium and silver ions. The phase of composition AgSbMoO6 with not potassium ions was first obtained. Proposed and confirmed by full profile analysis space-filling model in this compounds for the space group Fd3m.
