Abstract: The temperature-frequency properties of samples of natural disordered carbon were studied in the frequency range 50 kHz – 10 MHz and temperatures 120–420 K. A consistent increase in conductivity with increasing temperature and an exponential decrease in conductivity with increasing frequency were found. The revealed temperature-frequency properties are compared with various structural models of the structure of natural disordered carbon.

Keywords: natural disordered carbon, conductivity, impedance, temperature-frequency properties.
