Abstract

The aim of the invention is to increase a final product percentage, i.e. a fullerene content in a fullerene-containing black and to improve the stability thereof. The second aim of said invention is to increase the running time of a reactor operation cycle by reducing the frequency of technological cleanings of a processing chamber. The novelty of the inventive method for producing a fullerene-containing black consisting in evaporating graphite in an inert gas atmosphere by an electric arc between coaxial graphite electrodes disposed in the reaction volume of the processing chamber, in transferring the thus obtained products by an inert gas flow and in subsequently deposing said products in a black storage tank in the form of a fullerene-containing black, lies in that the electric arc and the reaction volume of the processing chamber are exposed to the action of continuous video pulse packets supplied directly to the graphite electrodes. The packet length ranges from 2?10-4 to 2?10-3 sec, the pulse ratio in a packet varies within a range of 10-100 and the power ranges from to 15 W. The second aim is attained by the fact that the wall of the processing chamber and of the black storage tank are exposed to the action of modulated reversed-polarity pulses whose repetition frequency ranges from 50 to 500 Hz and power from 1 to 10W and the walls of the lower part of the processing chamber are exposed to a pulsed magnetic field whose frequency ranges from 3 to 15 Hz and magnetic induction from 0.05 to 0.1 tesla.

The impact of the directive of the practical operation is completely eliminated by the magnetic processing chamber. The essence of the process is that, in most cases, the external part of the working camera emits pulses of a constant frequency of 1 - 5 The varying magnitude of the magnetic field leads to vibrations of the magnetization of the metal being cleaned, which leads to an increase in the magnitude of the magnetism. For the most part, slags do not possess magnetic properties, that is, between the magnetic material of the camera body and slag, the result of this shift is a result of The resulting small partitions of the large partitions and the disposable slag are accumulated in the base of the disposable part of the bottom part of the receiver. The elimination of the listed factors makes it possible to increase the continuous cycle by at least two times and to save the time spent on the whole.
