| Popis: | A method has been proposed for simulating the gas-dynamic conditions for the synthesis of molybdenum and its carbides in a radiofrequency induction plasma reactor with a vortex gas supply. A homogeneous flow of a mixture in a turbulent mode has been considered, taking into account inductive heating and the influence of the electromagnetic field force on the plasma motion. The composition of the transformation products has been determined in accordance with the results of thermodynamic calculations. The effect of the main synthesis products on the temperature field and flow in the reactor has been taken into account. The possibility of using a thermal, quasi-equilibrium argon–hydrogen plasma for the production of molybdenum and its carbides Mo2C and Mo3C2 from volatile fluoride and, as a reference, tungsten and its carbide WC has been explored. These results have been compared with those obtained earlier for boron, silicon, and their carbides. |
