In order to establish an evaluation method/numerical simulation for nuclear reactor safety under severe accidental conditions, it is necessary to obtain the physical properties, especially fluidity of the relevant molten materials at very high temperatures. In this study, thermophysical properties such as density and viscosity were obtained for (Fe $_{2}$ O $_{3}$ ) $_{0.95}$ -(SiO $_{2}$ ) $_{0.05}$ , which is a representative composition in the early stage of severe accident. (Fe $_{2}$ O $_{3}$ ) $_{0.95}$ -(SiO $_{2}$ ) $_{0.05}$ is produced by the contact between the molten oxide of steel, which is the main component of the reactor, and SiO $_{2}$ , which is the main component of concrete. As a result, the physical properties of the (Fe $_{2}$ O $_{3}$ ) $_{0.95}$ -(SiO $_{2}$ ) $_{0.05}$ mixture were almost the same as those of Fe $_{2}$ O $_{3}$ obtained in previous studies, and it could be concluded that a small amount of SiO $_{2}$ (about 5 mol.%) did not significantly affect the fluidity of Fe $_{2}$ O $_{3}$ .
