Abstract: Apparatus for preparing carbides from a powdered charge of carbon and oxygen-containing compounds of elements that can form carbides comprises an inductor for the induction heating of the charge to the reaction temperature with continuous compacting thereof. The powdered charge is heated by inducing in it high-frequency currents uniformly throughout the entire induction volume to the depth of not less than the radius of the charge column. A tubular reactor is enclosed inside the inductor which is a high-frequency generator. The reactor is manufactured out of nonmagnetic material. The reactor has slots in its wall that are filled with a dielectric material. A loading device provided with a pusher is mounted at a top portion of the reactor, and an unloading device provided with a valve and a receptacle is located at the bottom portion of the reactor.
