Özet:

 

KHCO3 compound was characterized in three principle  realms: for its dielectric properties as a function of temperature and  frequency in the ranges 300--370 K and 50 Hz to 1 MHz, respectively;  bulk conductivity as a function of temperature, via impedance  technique; and relaxation time as function of temperature.  Variations  of the bulk conductivity and relaxation time with temperature have  been found to yield two segments, with two different activation  energies.  The activation energy for the two segments due to bulk  conductivity have been found as 1.96 eV and 1.85 eV, while the  activation energy due to relaxation have been found to be 1.85 eV and  1.83 eV. The phase transition which was detected by DSC at T = 322 K  has been verified by the dielectric and conductivity measurements.
