ABSTRACT OF THE DISCLOSURE: Spherical particles formed a ceramic oxide material and possessing a predetermined particle volume are produced by forming droplets of a solution of both a salt of the metal and a resin, the droplets being of a size sufficient to yield particles of the aforesaid volume, gelling the droplets by feeding them to a liquid gelling agent therefor and calcining the gelled particles. The viscosity of the solution being fed to the liquid gelling agent is adjusted continuously or at regular intervals and kept to a predetermined value by indirect heat exchange with a heating or cooling medium so that the particles produced from the droplets are spherical. The invention enables one to produce ceramic particles of various kinds, and in particular spherical particles for use as nuclear fuel, magnetic particles and catalyst particles, depending on the composition thereof.
