摘要

Formation of two pyrochlore ceramics with formulations CaZr_(0.25)U_(0.75)Ti_2O_7 andrnCaUTi_2O_7 within the temperature range 1000-1500 0C from batches prepared by grinding ofrnoxide powders in a mortar and an activator with hydrostatic yokes AGO-2U as well as soaking ofrna Ca, Zr, and Ti oxide mixture with uranylnitrate solution was studied. The pyrochlore ceramicsrnare produced through intermediate calcium uranate formation. Phase formation reactions in thernbatch pre-treated in the AGO-2U unit were completed within the temperature range 1000-1100rn℃ that is lower than in the batches prepared by two other methods.
