In this paper, we report some physical properties of AgAlP 2 O 7 compound obtained through the standard solid-state reaction technique. AgAlP 2 O 7 has been studied by X-ray diffraction, Raman spectroscopy and impedance spectroscopy. The title compound crystallized at room temperature (T = 300 K) in the monoclinic system with P2 1/c space group. The electrical properties were studied over a wide range of temperature (440-640 K) in the frequency range of 40 Hz-10 MHz. Study of frequency dependence of AC conductivity suggests that the material obeys the Jonscher's universal dynamic law. The conductivity is equal to 9.37 9 10 -5 X cm -1 at 640 K, and it is thermally activated with activation energy of 0.76 eV. The variation of DC conductivity with temperature follows the Arrhenius behavior. The calculated values of s decreased with temperature. This behavior reveals that the conduction mechanism is correlated with barrier hopping. The binding energy W m and the hopping distance R x were deduced.
