Title:
セラミックス微粒子の製造方法及びそれに用いられる球状セラミックス成形体の製造装置
Document Type and Number:
Japanese Patent JP5473231
Kind Code:
B2
Abstract:
Provide 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.
