“…The trend of the strength data for alumina is consistent with our data in Fig. 13, but different than that of Akopov and Poluboyarinov [33]. [28,29], Lipi nska-Chwałek et al [30], and Wang et al [31] are shown superimposed on the data generated in the present study.…”

“…The availability of flexural strength data is more limited still. Akopov and Poluboyarinov [33] present flexural strength data for ceria up to 1350 C, but the details of the experimental technique are not provided. The new data generated here are compared to available room temperature data of previous authors in Sec.…”

This work reports the elastic modulus and four-point flexural strength of a gelcast ceramic, cerium dioxide (ceria), with a microporosity of nominally 20% and a grain size of 11 μm from 23 to 1500 °C. The data augment the sparse data published for ceria and extend previous results by 150 °C. The ceria tested is representative of that constituting the ligaments of a reticulated porous ceramic. The elastic modulus decreases from 90 GPa at 23 °C to 16 GPa at 1500 °C. The flexural strength is 78 MPa below 900 °C and then decreases rapidly to 5 MPa at 1500 °C. These trends are consistent with data reported for other ceramics. Comparing the measured elastic modulus to prior data obtained for lower porosity shows the minimum solid area (MSA) model can be used to extend the modulus data to other porosities. Similarly, the flexural strength data agree with prior data when the effects of specimen size, porosity, and grain size are taken into account.
