Summary:A method for the preparation of a highly dispersed powder of tin monoxide (SnO) by the evaporation/condensation method under heating the initial material with focused radiation of a subterahertz gyrotron with a frequency of 0.26 THz and a power of 1 kW is investigated. The process is carried out with a purge with nitrogen that is inert with respect to SnO. A powder with a SnO content of 92 wt % is obtained. The specific surface area of the powder is 7.20 m 2 /g, which corresponds to an average particle size of 130 nm. The characteristics of the obtained powder are analyzed. The applicability of the experimental setup for the production of highly dispersed powders from compounds that require special gas conditions in the evaporation/condensation process is demonstrated.
