ABSTRACT:
Powders suitable as electographic toner and/or carrier particles and other powders which utilize a liquid dispersant are produced by limited coalescence techniques. The dispersant is removed by mixing the suspension of coalesced droplets with a sufficient amount of an extracting liquid to cause the dispersant to diffuse out of the coalesced droplets into the extracting liquid.
