Özet:

 

The total conductivity of KHCO3 compound is studied in the  frequency range 50 Hz-1 MHz and in the temperature range 300-370 K.  The conductivity frequency dependence relation is divided into three  regions: one at low frequency (dc conductivity), while the others  appear at a moderate and relatively higher frequency range.  In  general, the conductivity frequency dependence conductivity obeys a  double power law relation, stot = sdc + Awp +  Bwq.  The powers p and q have been found to be in the range 0 to  1 and 1 to 2, respectively.  The attenuation coefficient b of  KHCO3 compound was studied over a temperature range from room  temperature up to 370 K. The general behavior showed two essential  activated regions.  The activation energies are estimated and  discussed.
