Abstract
A process for preparing discoidal powder particles, characterized by dissolving wet nitrocellulose in an appropriate solvent to form a lacquer having a viscosity between about 12 and about 100 seconds, at 60º C, extruding the lacquer through at least one hole to a medium aqueous non-solvent, cut sections similar to disks from the extruded lacquer as it emerges from the orifice while in contact with the non-solvent medium to form a suspension of lacquer sections in the non-solvent medium, heat the resulting suspension to evaporate said solvent of said sections while retaining its disc-like shape and the resultant solid particles of nitrocellulose are separated from the suspension in a disk-like manner.
