Annotation

The density of a

$\mathrm{UO}_2$ –

$\mathrm{ZrO}_2$ melt (atomic ratio

$\mathrm{U}/\mathrm{Zr}= 1.528$ ) is experimentally measured by a pycnometric method in the temperature range of

$2973$ –

$3373$ K. The found temperature dependence of density has the form

$\rho(T)=(7.0\pm0.01)-(4.5\pm0.4)\times10^{-4}\times(T-2973\mathrm{K})$ , g/cm

$^3$ . The temperature dependence measured enables one to calculate the values of the density of

$\mathrm{UO}_2$ –

$\mathrm{ZrO}_2$ melts depending on the temperature and composition for any atomic ratio

$\mathrm{U}/\mathrm{Zr}$ .
