Abstract
When a particulate material under molten or dissolved state is atomized by means of a fluid nozzle or a rotary disc type atomizer, a high voltage is applied to obtain particles which are uniform in shape and, for example, spherical with a narrow particle size distribution. Further, if necessary, the particles obtained are subsequently encapsulated in the continuous step.
