Melting points of CeO2-ZrO2 solid solutions were evaluated by the containerless method with laser heating, and their thermal properties, e.g. heat capacity and thermal conductivity, were measured by the lase flash analysis. In addition, melting points of UO2-ZrO2 as well as CeO2-ZrO2 were calculated by the molecular dynamics method.
