摘要：

It is shown (using Controlled transformation Rate Thermal Analysis) that the residual pressure during the two last dehydration steps of hexahydrated uranyl nitrate determines the surface area of the final UO3 (2 to 45 m2 g-1 as this pressure drops from 100 to 5 x 10(-2) mbar) due to the formation of two different nitrates.
