| titleOfInvention | Method for obtaining uo3 of high specific surface from hydrated uranyl nitrate |
| abstract | Method for obtaining uranium trioxide of high specific surface by thermal denitration of hydrated uranyle nitrate having the formula UO2(NO3)2,xH2O, wherein 2 <=x<=6, characterised in that, in a first stage, said nitrate is treated in liquid form at a temperature comprised between 160oC and 269oC until a solid phase is obtained containing at least 55% by weight of uranium and, in a second stage, said solid phase is progressively heated to a temperature at the most equal to 600oC, according to a temperature gradient not exceeding 1000oC per hour, and is maintained at that temperature not exceding 600oC up to the obtention of a second solid phase comprised of UO3 of high specific surface. UO3 produced has a specific surface of at least 10m2.g-1. |
