Summary

CaO and CeO2 doped nanocrystalline ZrO2 powders were synthesized using a propellent combustion synthesis process. The compositions contained 2 to 10 mol% of CaO and 4 to 20 mol% of CeO2 in ZrO2. The powders were characterized by x-ray diffraction, Raman spectroscopy and transmission electron microscopy. The results indicated that the as-synthesized powders were in the tetragonal phase and not in the cubic phase. There is also evidence of extension of solid solubility because of the non-equilibrium nature of the process. These results reduce ambiguities presented in the literature.
