Abstract

Precipitates formed by the neutralisation of Pu(III), Pu(IV), Pu(V), and Pu(VI) solutions were characterised by HRTEM, SAXS, and XRD in the suspensions. PuO₂ nanoparticles uniform in size (typical diameter around 2.5 nm) and phase composition were observed in all cases under equilibrium conditions. For Pu(VI), the precipitation reactions proceed via an intermediate product.
