PURPOSE:To produce ceramic hollow particles by performing one process coating core material particles with a ceramic powder in a predetermined thickness within a short time by one manufacturing apparatus. CONSTITUTION:In a method for producing ceramic hollow particles, a process coating the surface of spherical core particles 11 with a predetermined particle size composed of an org. material with a ceramic powder 21 through a binder is performed by fluidizing the total amt. of the core particles 11 to spray a predetermined amt. of a binder soln. 31 containing the org. material, an inorg. material or both of them on the core particles 11 and also supplying a predetermined amt. of the ceramic powder 21 to the core particles. |
