Development and Test of a Technique to Create Liquid Suspensions of Sub-Micron Metallic Particles.
Abstract
An investigation has been carried out to find a practical way to create liquid suspensions of sub-micron metallic particles. Particles of suitable size and purity were produced by a technique developed at Oak Ridge National Laboratory using the Exploding Wire Aerosol Generator (EWAG). To introduce the particles from the resulting aerosol into a liquid, a prototype Particle Transfer Device (PTD) was devised and constructed. This device uses a unique Collimated Hole Structure (CHS) to form large quantities of tiny bubbles within the liquid. Capture of the particles within these bubbles is by diffusion to the bubble walls. Initial qualification tests substantiated the concept, but the efficiency was quite low because of unanticipated electrical effects. Corrective actions are suggested which may enable the full potential of the concept to be realized. (Author)
