THE THERMAL EXPANSION AND HEAT CAPACITY OF UO$sub 2$ TO 2200 C
Measuremerts of the enthalpy and heat capacity of UO/sub 2/ in the temperature range of 900 to 2200 deg C were made by employirg the drop technique in conjunction with an adiabatic calorimeter. The following heat capacity relationship was obtained: Cp = 7.919 x 10/sup -2/ --19.468 x 10/sup -6/T + 15.09 x 10/sup -9/T/sup 2/, where Cp is in cal/g deg C and T is in deg C. The linear thermal expansion of UO/sub 2/ was measured by sighting paired filar micrometer telescopes on fiducial marks on either end of a 0.25-in. dia, 2.5-in. long specimen. The equation for the coefficient of linear thermal expansion is alpha (in./in. deg C) = 6.797 x 10/sup -6/ + 5.792 x 10/sup -9/T. Data are presented in graphs. (M.C.G.)
