Fabrication of Pyrochlore Gd2Zr2O7 by High Temperature Solid State Reaction
In order to investigate the fabrication of pyrochlore Gd2Zr2O7, Gd2O3 and ZrO2 were used as raw materials in the process. Pyrochlore Gd2Zr2O7 were fabricated by high temperature solid state reaction at 1100 – 1600 °C under atmospheric pressure for 72 h. XRD and SEM studies were exploited to characterize the crystal structure and microstructure of the synthetic samples. The results revealed that Gd2Zr2O7 with a single pyrochlore structure was fabricated successfully at 1500 °C. The microstructure of the sample was uniform and dense, and the grain size was in the range of 1 - 3 μm.
