[en] The thermodynamic and transport properties of solid and liquid UO₂ are tabulated as a function of temperature. Properties are given for the temperature range 298.15 K to 3120 K for solid UO₂ and from 3120 to 6000 K for liquid UO₂. Thermodynamic properties tabulated include enthalpy, heat capacity, pressure, density, instantaneous thermal expansion coefficient, compressibility, thermal pressure coefficient, and speed of sound. Tabulated transport properties include thermal conductivity, thermal diffusivity, emissivity, electrical conductivity, and viscosity. Tables are given in SI units and cgs units
