摘要：A functional particle is manufactured by a method including an aggregatingstep, a depressurizing step, and a cooling step. In the aggregating step, the functional

particle is obtained by flowing a mixed slurry containing a core particle and a shellparticle through a coiled pipeline while heating the mixed slurry to a glass transitiontemperature or higher of the core particle, to deposit the shell particles on the surfaceof the core particle. In the depressurizing step, the grain size of the functional particle iscontrolled and the coarse particle is pulverized to make the grain size of the functionalparticles uniform. In the cooling step, re-aggregation of the functional particles withunified grain size is prevented.
