“…The open-framework metal phosphates, characterized by their high ionic conductivity, have been extensively studied, which might find applications such as prospective materials in technology, viz., in electronic devices and as solid electrolytes with high thermal resistance and as potential devices in space application, sensors, solid-state laser materials, piezoelectrics, luminescence, ceramics, catalysis, adsorption, ionic conductors, and magnetic materials [1][2][3][4][5][6][7].…”

The α-Zn 2 P 2 O 7 compound was obtained by conventional solid-state reaction. The sample was characterized by X-ray powder diffraction, solid state 31 P NMR MAS, and electrical impedance spectroscopy. The solid state 31 P MAS NMR, performed at 121.49 MHz, shows three isotropic resonances at −21.1, −18.8, and −15.8 ppm, confirming the non-equivalency of the three PO 4 groups in the α-Zn 2 P 2 O 7 form. They are characterized by different chemical shift tensor parameters with the local geometrical features of the tetrahedra. Electrical impedance measurements of β-Zn 2 P 2 O 7 , form stable for temperature greater than 403 K, were performed as a function of both temperature and frequency. The electrical conduction and dielectric relaxation have been studied. The AC conductivity obeys the universal power law. The approximation type correlated barrier hopping model explains the universal behavior of the n exponent. The impedance plane plot shows semicircle arcs at different temperatures, and an electrical equivalent circuit has been proposed to explain the impedance results. The circuits consist of the parallel combination of bulk resistance R p and constant phase elements CPE. The simulated spectra show a good correlation with the experimental data.

“…The metal phosphates are of considerable industrial interest, which might find applications such as prospective materials in technology, electronic devices and as solid electrolytes with high thermal resistance and as potential devices in space application, sensors, solidstate laser materials, piezoelectrics, ceramics, catalysis, adsorption, ionic conductors, and magnetic materials [1][2][3][4][5][6][7]. Crystals of double phosphates with general formula A 2 BP 2 O 7 containing simultaneously an alkaline ion (A + ) and a divalent cation (B 2+ ), form a large family of materials [8,9].…”

NaAgPbP 2 O 7 was prepared with a solid-state reaction. The electrical properties were investigated by using impedance measurements in the frequency range from 200 Hz to 5 MHz with the TEGAM 3550 ALF automatic bridge monitored by a microcomputer between 581 K and 703 K. The Z′ and Z″ versus frequency plots are well fitted to an equivalent circuit model. The conductivity data obey the universal power law. The conductivity in the material is due to the hopping of monovalent ions parallel to (001) plane.

“…Inorganic phosphates cover a large class of diverse materials whose applications include: catalysts, solid electrolytes for batteries [1][2][3], linear and non-linear optical components [4,5] and laser materials [6,7]. However, the study of phosphates has become more popular particularly, after the development of NASICON groups of fast ionic conductors [8][9][10].…”
