Abstract
The process of preparing powder particles having a desired particle shape, comprising the steps of: providing a paint solution having a film-forming portion and a first solvent portion, forming droplets containing the film-forming portion and the solvent portion, by contacting the paint solution with a second solvent which is partially miscible with the first solvent and in which the film-forming portion is non-soluble, the second solvent being substantially saturated with the first solvent, diluting said droplets with a sufficient quantity of a third solvent which is at least partially miscible with the first solvent and in which the film-forming portion precipitates as powder particles, and controlling the shape of the powder particles by regulating the dilution of the first solvent in the droplets.
