Abstract
Procedimiento para la obtención de polvo de dióxido de uranio, según el cual UF6 gaseoso se alimenta simultáneamente con NH3 y CO2 a un recipiente con agua, el carbonato de uranilo amónico (AUC) allí precipitado se separa por filtración de la lejía madre y después se transforma en un lecho fluidificado con ayuda de vapor de agua, como gas soporte, y un gas de efector reductor de UO2, caracterizado porque se reduce con el agente reductor NH3.
