Conditions

Temperature
150 °C

Procedure

The same procedure is followed as in Example 1. Thus, a uranium(IV) solution is first of all prepared by dissolution of 4 g of UCl4 in a 4M hydrochloric acid HCl solution in order to obtain a uranium concentration of 0.7M. This solution is mixed with a 5M phosphoric acid solution in the phosphoric acid/uranium(IV) molar ratio of 3/2 with an excess of 2% of phosphoric acid. The mixing is carried out in a container which is subsequently closed and which is heated, as in Example 1, at a temperature of 150° C. on a sand bath for 1 week. Under these conditions, the initial gel is converted by heating to a crystalline powder.
