Popis:	The paper describes the experimental setup and some results of experiments on the production of highly dispersed metal oxides powders using the example of tungsten trioxide WO3 by the evaporation-condensation method when the initial material is heated by focused radiation of 0.53 THz / 240 W gyrotron. By focusing the gyrotron radiation, it was possible to achieve an intensity of several kW/cm2 on the surface of the evaporated initial sample. The use of a system with a rotating crucible made it possible to increase the evaporation rate of the substance by 3–4 times, which is very important in conditions of a lack of power.
