Filippov, A. Karelin, O. Lobas, A. Papkov, A. Zhiganov, L. Mishina, V. Shamin] To obtain actinides oxides as microspheres, the internal gelation method is suggested. As a dispersive medium, we propose to use hydrocarbons containing fluorine and having a density of 2000 kg/m3. These substances are chemically inert, fire-proof, non-toxic and resistant to γ-radiolysis. Using a fluorohydrocarbon-containing liquid creates in the gelation column a vertical temperature gradient with minimal temperature in the zone of working solution dispersion and maximal one in the upper part of the column. This article treats the mechanism and model of a drop-forming process to control the process of microspheres formation, in which a working solution is dispersed in a dispersive medium.
