摘要：

The products obtained by ion exchange of zirconium phosphate loaded with Ag+ (from 13% to 96% of conversion) have been characterized by thermal and X-ray methods. The materials maintain a layered structure until around 550-600°C, with a d002 of about 7,6-7,8 A. At low Ag conversion solid solutions can be obtained. For all samples, above 600°C the layered structure disappears and the phase AgZr2(PO4)3 is produced. Other phases, ZrP2O7, Ag4P2O7 or Ag3PO4 (depending on the initial composition) are formed together with AgZr2(PO4)3. The conditions of formation and possible transformation of some of these phases are discussed. © 1979.
