Abstract

A manufacturing method for ceramic microspheres including the steps of; forming a suspension of ceramic fine powders as a dispersed phase and water as a dispersion medium; dispersing the suspension as droplets in a high boiling point liquid which has substantially the same specific gravity as the suspension and which is immiscible with water and nonreactive with the ceramic fine powder to make spherical particles; and subjecting the resultant product to drying and calcination.
