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.
