Based on the special experiment project of training special skill and enhancing compressive quality of students, Ce0.8Sm0.2O1.9 powders are prepared by chemical eopreeipitation method and are pressed into small pieces and small bars with dimensions of 5×5×50mm, which are applied to study the sintering shrinkage process. The structure of the material is characterized by XRD, and the density of the specimens is determined by Archimedes method. AC impedance spectroscopy is performed on the pieces from 400 to 850℃. The result shows that student master the principle of coprecipitation, measurement of consistency and electricity property.
