A novel, fast, and cheaper method has been developed for the synthesis of fully cubic calcium‐stabilized zirconia (ZrO 2 ) of composition Ca 0.1 Zr 0.9 O 1.9 by dissolution of calcium oxide in monoclinic ZrO 2 for the first time using microwave energy. In this process, the precursors have been prepared by the mixed‐oxide method taking the constituents in their stoichiometric ratio. The samples have been allowed to absorb microwave radiation in the presence of a polymeric susceptor. The susceptor absorbs the microwave radiation at room temperature and increases the temperature of the sample, where it starts interacting with microwave radiation. The susceptor burns off at a higher temperature without reacting with the sample. The cubic Ca 0.1 Zr 0.9 O 1.9 has been prepared at a temperature of 1100°C within 5 min.
