The two-phase model of the fluidized bed has been analyzed and validated with the data from pilot furnace with a throughput capacity of 10 kg/hour built in this research.. The data was used to derive an equation that allows estimating the value of specific electrical resistance for the natural graphite-based precursors entering the fluidized bed reactor. Data collected in the course of graphite refining activity demonstrated that difference between the calculated and measured values of specific electrical resistance of fluidized bed does not exceed 25%. It is concluded that due to chaotic nature of electrothermal fluidized bed reactors this discrepancy is acceptable. The numerical relationships
