Conclusions

The studies of the stabilization of ZrO2 by rare-earth oxides alone and in combination with MgO, CaO, and Y2O3 have made it possible to select compositions suitable for preparing a grainy-structure ceramic.

The study of three different methods showed that the most thermally stable and thermal-shock resistant is the grainy-structure ceramic based on fused materials.

Tests of the ceramic as the electrodes for the test channel of the MHD generators have confirmed its excellent thermal stability and thermal-shock resistance.
