The thermal expansion of a ZrO₂-20 mol% Gd₂O₃ pellet has been systematically investigated using a thermo-mechanical analyzer in the temperature range of 293-1773 K. Variations in the thermal expansion coefficient and density upon temperature change were calculated using the thermal expansion data. The average linear thermal expansion coefficient of theZrO₂-20 mol% Gd₂O₃ pellet was found to be 9.522 × 10^-6 K^-1 in the range of 298-1073 K. This value is smaller than that of ZrO₂ and larger than that of Gd₂O₃. Further, with an increase in temperature to 1773 K, the density of ZrO₂-20 mol% Gd₂O₃ pellet was found to decrease to 94.98 % of the initial density at 293 K.
