“…of a mixture of actinides precursor solutions in highly coordinating organic media containing benzyl ether, oleic acid and oleylamine [10][11][12] . At the opposite of the length scale, the production of uranium oxide spheres, typically in the 100 -500 µm range, has been reported for a long time from the initial precipitation of precursors through sol-gel processes 13,14 .…”

“…The spherically shaped precipitate is thermally treated and can afterwards directly be used as particle fuel [9] or compressed into the commonly used fuel pellets [10]. The IG process offers a dust-free fabrication route to convert mixtures of different metal cations into a homogeneous precipitate and was used to prepare MOX particles [11] and U/Pu nitride particles [12].…”

“…ZrO 2 microsphere is a good template for the UC 2 or UO 2 kernel of the fissile fuel particles, which has been applied to high‐temperature gas cooled reactor (HTGCR) . ZrO 2 microspheres are typically fabricated by an internal gelation process to achieve the good sphericity, uniform size, and homogeneous structure .…”

Droplet Micro‐Reactor for Internal Gelation to Fabricate ZrO₂ Ceramic Microspheres

et al. 2016

A droplet micro‐reactor was developed to realize the internal sol–gel reaction of ZrO2 inside the droplet. The reactants are only allowed to combine when the droplet forms, meanwhile, they are able to mix well and react to form gel particles with a proper designed structure of the micro‐reactor. In this condition, the mixing efficiency was determined by the structure of the micro‐reactor and the flow rate ratio of the two components. After sintering, ZrO2 ceramic microspheres are acquired with high sphericity and narrow size distribution. This droplet micro‐reactor overcomes the gelation of the premixed sol and reactant in the channel, and it has been demonstrated to be more stable with a longer running time.
