【 摘 要 】

Yb_ð‘�?Gd_{2â€�?�ð�?��?}Zr₂O₇ (ð‘�? = 0, 1, 2) ceramics were pressureless-sintered using ceramic powders acquired by chemical-coprecipitation and calcination methods. Heat capacities of Yb_ð‘�?Gd_{2â€�?�ð�?��?}Zr₂O₇ were measured with a heat flux-type differential scanning calorimetry in the temperature range of 298â€�??1200 K. At 298 K, the heat capacities of Gd₂Zr₂O₇, YbGdZr₂O₇ and Yb₂Zr₂O₇ were 214, 221 and 230 J.K^-1 mol^-1, respectively.
