Kool, L B; Nolen, Jr, R L; Solomon, D E

A method of adjustably tailoring the effective bulk density of a solid material in which a mixture comprising the solid material, a film-forming polymer and a volatile solvent are sprayed into a drying chamber such that the solvent evaporates and the polymer dries into hollow shells having the solid material captured within the shell walls is described. Shell density may be varied as a function of solid/polymer concentration, droplet size and drying temperature. An example of the application of this technique is for tailoring a working fluid for MHD generators made of cesium carbonate suspensions in toluene.
