Process for producing ceramic fine particles, and ceramic fine particle producing apparatus used therein
Abstract:
Provided are a ceramic-fine-particle producing process making it possible to produce, with ease, ceramic fine particles which have a spherical shape close to a complete round and an excellent mono-dispersibility, and are made only of a solid component of a simple ceramic material without making a fine channel structure complicated, and an apparatus used therein for producing ceramic fine particles. The process includes the step (S100) of feeding a dispersion phase made of an aqueous liquid containing a gelling agent to act upon cooling and a ceramic material into a continuous phase made of an oily liquid containing a surfactant, thereby producing fine droplets; the step (S110) of collecting and cooling the produced fine droplets; the step (S120) of washing the cooled fine droplets; the step (S130) of drying the washed fine droplets; and the step (S140) of firing the dried fine droplets.
