摘要: Zirconia-based ceramic oxides Zr0.90Y0.06Ce0.02X0.02O2−δ (X = Ca, Fe, La, Sr, and Mg) were prepared by conventional microwave processing. The precursors of a mixed oxide method calcined at 600°C in an electric furnace. powders consolidated pellet form sintered furnace 1400°C for 6 h compared using energy 20 min. structure microstructure products obtained both methods studied x-ray diffraction scanning electron microscopy. Their density microhardness also compared. electrical conductivities these samples alternating current impedance spectroscopy. analysis the aand shows that have uniform grain growth, higher density, conductivity than corresponding conventionally products. sample composition Zr0.90Y0.06Ce0.02Ca0.02O2−δ was found to highest microhardness, as well among all
