HIGH-TEMPERATURE INTERACTION OF TETRAFLUORIDE OF URANIUM, TERBIUM AND CERIUM FLUORIDES WITH THE CARBONATE AND SODIUM SILICATE
The method of the differential-thermal analysis in combination with RFA studied reactions of UF 4, CeF 3 and TbF 3 with air oxygen in the presence of Na 2CO 3 or Na 2SiO 3 in the range of temperatures from 25 to 800 °C. It is shown that firm products of reaction are уранаты sodium, cerium (IV) oxide, terbium (III) and NaF oxide, and gaseous products – SiF 4 and CO 2.
