Аннотация:A multitemperature model of conjugated heat transfer during the synthesis of zirconium nitride isdeveloped. The model includes the following parameters: the temperature of the solid phase consisting ofmicrometer-sized particles of , , and ; the temperature of the gas phase comprised of componentsCO, CO2, O2, and N2; the temperature of the reactor vessel made of porous graphite; and the temperature ofthe tungsten alloy layer, to the electrodes of which the potential difference is applied. The operation regimeswith a multistage air flow at the reactor inlet for reducing the carbon impurity are studied. A decrease in theporosity by three orders of magnitude relative to the value at the initial point in time is demonstrated. Theobtained results are in satisfactory agreement with the experimental data.
