Abstract
Compositions in the (AgxNa1-x)2Nb4O11 solid solution have been prepared by a conventional
solid state method. Composites containing Ag2Nb4O11 have been shown to be ferroelectric
and the Curie temperature shown to decrease from 149 °C at x = 1 to 62 °C at x = 0.7. Roomtemperature
compositions with x ≤ 0.7 are monoclinic, while those with x ≥ 0.8 are
rhombohedral with structures consistent with the relevant end-members. At x = 0.75, the
structure was mainly rhombohedral but with coexistence of the monoclinic structure,
indicating the proximity of a phase boundary.
