Thermodynamic properties of tubular cobaltite Bi 3.7 Sr 11.4 Co 8 O 29MINUS SIGN ?
Original language description
We synthetized a tubular cobaltite Bi3.7Sr11.4Co8O29-delta ceramics and characterized it using X-ray diffraction (XRD) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS). The simultaneous thermal analysis (STA) revealed a veryunusual thermal behavior which was eventually ascribed to metastability of tubular phase at lower temperatures. The heat capacity and enthalpy increments were measured by physical property measurement system (PPMS), differential scanning calorimetry (DSC) and drop calorimetry. The oxygen non-stoichiometry was determined using thermogravimetric measurement (TG) and reduction in hydrogen atmosphere. Above room temperature the temperature dependence of the molar heat capacity was derived by simultaneous least squares method from DSC and enthalpy data. The heat capacity was also analyzed in terms of a combined Debye-Einstein model. The molar entropy s(m)(o) (298.15)= 1349.45J mol(-1) K-1 was evaluated from the low temperature heat capacity
