摘要：

Using simultaneous thermal analysis (TG + DSC), the heat capacity and non-stoichiometry of BaCuO2+x in O2 atmosphere have been investigated. The results are formulated as 2.11 +/- 0.02 > 2 + x > 2.00 +/- 0.02 for 600-degrees-C < t < 900-degrees-C. The heat capacity C(p) = 0.405 + 1.05 x 10(-4)t (J/g-1K-1) was measured in the temperature range 40-degrees-C < t < 400-degrees-C. The uncertainty of less than 2% is due to special selection of the sample masses.
