The regularities of the acoustic method of separation of ultrafine powders — the redistribution of particles into nodes and the antinodes of a wave on the surface of a transversely oscillating plate — are considered. Experimental data on the efficiency of the separation of silica nanoparticles by this method were obtained. For the first time, the dependence of the characteristic size of the particle separation on the amplitude of oscillations smaller than the thickness of the Stokes boundary layer was revealed.
