Heat capacity measurements on Yb_xGd_(2-x)Zr_2O_7 (x = 0, 1, 2) ceramics by differential scanning calorimetry

摘要

Yb_xGd_(2-x)Zr_2O_7 (x = 0, 1, 2) ceramics were pressureless-sintered using ceramic powders acquired by chemical-coprecipitation and calcination methods. Heat capacities of Yb_xGd_(2-x)Zr_2O_7 were measured with a heat flux-type differential scanning calorimetry in the temperature range of 298-1200 K. At 298 K, the heat capacities of Gd_2Zr_2O_7, YbGdZr_2O_7 and Yb_2Zr_2O_7 were 214, 221 and 230 J?K~(-1) mol~(-1), respectively.
