ABSTRACT:
Particles (10) contained in a mass of liquid etchant (12) and being wetted and etched thereby are moved into a mass of an inert, etching-terminating liquid (14) which abuts the etchant mass by overcoming surface tension forces exerted on the particles by the etchant at the interface (16,70) of the liquid masses. A vortex (24) of the inert liquid (14) is forced and in turn forces a conformal vortex (60) of the etchant (12) with the particles (10) therein. Turbulence at the interface (70) of the vortices (24,60) and vortex-generated centrifugal force on the particles (10) overcome the surface tension forces, and the particles move into the inert liquid (14).
