Popis:	The modification of polycrystalline oxides (SnO2 and ZnO) under the action of a nanosecond high-power ion beam (HPIB) with current densities of 50–150 A/cm2, which is accompanied by melting of initial particles of the surface layer, is investigated. It is established that submicron-sized particles of tetragonal SnO whose average size is 210 nm are formed on the SnO2 surface irradiated by an ion beam with a current density of 150 A/cm2. These particles have pronounced crystallographic faceting. When ZnO is irradiated by HPIBs with different current densities, a thin Zn film is formed in the sintered surface layer. Possible mechanisms of the observed conversions are discussed.
