摘要：
.The structure of the powder of Azure A chloride was analyzed by the X-ray diffraction and scanning electron microscopy techniques. The dielectric properties and electrical conductivity were studied for bulk Azure A chloride as pellets in the frequency range of 100-5000kHz. The frequency exponent decreased with the raise in temperature. The correlated barrier hopping is the convenient mechanism for AC conduction in bulk Azure A chloride. The temperature dependence for AC conductivity followed the Arrhenius variation with varied activation energies at certain frequencies. The observed behavior of the dielectric constant and dielectric loss was investigated at different temperatures. The relation between the real and imaginary components of the complex impedance for bulk Azure A chloride was delineated in Nyquist plots at numerous temperatures.
