“…Rousseaux et al [46] reported that higher turbulent energy dissipation rate (for instance, at higher rotating speed) generally leads to a specific surface increase and to a decrease in the crystallite size based on precipitation of pseudo-boehmite. Manna et al [47] studied the sodium diuranate precipitation process in an agitated reactor where 8(N) NaOH solution was added in sodium uranyl carbonate solution. They reported that the mean particle size reduced with an increase in the impeller power number.…”

Ammonium diuranate (ADU) is an important intermediate for the production of uranium base fuel. Controlling morphology of crystalline ADU powders is very important as it is retained by its subsequent products. Because of the high level of supersaturation, the involved mechanisms of precipitation like primary nucleation, crystal growth, aggregation and breakage occur simultaneously and they control the morphology. Effects of concentration of uranyl nitrate solution, temperature and the mixing intensity have been investigated on the morphology, crystal structure and the other physical properties of ADU. Effect of temperature is found to be more dominant for controlling morphology.
