BULYCHEV, E.N. MURAVYEV, A.A. CHERNOV, M.A. KAZARYAN In this paper, a new form of plasma discharge in a liquid under intensive ultrasonic treatment exceeding the cavitation threshold has been explored in view of initiation of various physical and chemical processes. Furthermore, in this plasma discharge, nanoparticles of tungsten oxide with controlled shape and size of particles and narrow particles size distribution have been synthesized. Further research proved that ultrasonic cavitation during synthesis signifi cantly aff ects the physical and chemical characteristics of nanoparticles. Key words: Plasma, ultrasonic cavitation, nanoparticles, tungsten oxide. Contacts: E-mail: nbulychev@mail.ru Pp. 66-70.
