Melting points of CeO₂-ZrO₂-FeO_1+xmixtures were evaluated by the containerless method with laser heating, and their thermal conductivities and heat capacities were measured as well. Meanwhile, using the molecular dynamics technique, melting behaviors of UO₂(or CeO₂)-ZrO₂-FeO_1+xmixtures were evaluated.
