· Refractories (Engl. Transl.); (United States)
A systematic study has been made of the behavior of ZrO/sub 2/ stabilized with various oxides under the prolonged action of temperatures up to 2300 degrees C. The optimal concentrations of Y/sub 2/O/sub 3/, Nd/sub 2/O/sub 3/, CaO, and MgO in the zirconia refractories have been established. This ensures the successful service life of the articles under conditions of multiple prolonged action of high temperatures. The ultimately permissible temperature at which it is possible to operate the zirconia articles has been determined, with the stabilization of ZrO/sub 2/ by MgO it is 100 degrees C; with CaO, 2000 degrees C; and with oxides of rare-earth elements, more than 2300 degrees C.
