Refractories Aims and scope

Conclusions

We studied the influence of the form and amount of stabilizer and the synthesis schedules on the phase ratios in the approximate eutectic compositions for the systems ZrO2-Al2O3 (MgAl2O4, SiO2, mullite), and also the thermodynamic stability and mechanical properties of the ceramics based on them.

Stabilization of zirconia is possible in all the systems investigated; and the optimum amounts of stabilizing additions were determined for the stated synthesis cycles.

It is established that the most satisfactory mechanical properties are exhibited by specimens in the ZrO2-Al2O3 system with the use of 4% Y2O3.
