The process of graphitization of anthracite as a carbon component of self-baking electrodes is considered. Experimental studies of the physical properties of thermoanthracite by thermogravimetry and IR spectroscopy in the temperature range 400…1400 °C were performed. Regression models of the relationship between the structure of thermoanthracite, strength, thermal conductivity and resistivity and the temperature regime of anthracite calcination were created. Ref. 9, Tabl. 4, Fig. 7.
