“…There were metallic tungsten, titanium metal and graphite. All of these electrodes were used to obtain different compositions of ultrafine materials based on tungsten, boron, silicon, titanium, carbon [5,[7][8][9][10]. The generated plasma structure depended on the material of the acceleration channel, the material of the central electrode tip, the material of the electrical bridge between the electrodes of the accelerator, the gaseous atmosphere of the reactor.…”
