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 <sub>4</sub>, CeF <sub>3</sub> and TbF <sub>3</sub> with air oxygen in the presence of Na <sub>2</sub>CO <sub>3</sub> or Na <sub>2</sub>SiO <sub>3</sub> 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 <sub>4</sub> and CO <sub>2</sub>.
