摘要：

We have synthesized materials based on a silver titanium phosphate with partial substitution of tri-, tetra-, or pentavalent cations for titanium: Ag-1 +/- x Ti2-x M (x) (PO4)(3) (M = Nb5+, Ga3+) and AgTi2-x Zr (x) (PO4)(3). The materials have been characterized by X-ray diffraction and impedance spectroscopy and have been shown to have small thermal expansion coefficients. Their ionic conductivity has been determined. Silver ions in these materials are difficult to replace with protons.
