Low Temperature Heat Capacity and Thermodynamic Properties of Zinc Ferrite*
The heat capacity of zinc ferrite (ZnFe,O,) has been determined over the range 5 to 350°K. Molal values of C~,S’, and HO-H,O computed from the thermal data are 32,99&t-0.03 cal/deg., 36.01 f0.03 cal/deg., and 18,00&0.02 Cal, respectively, at 298,lS”K. A co-operative thermal anomaly associated with antiferromagnetic ordering occurs at 9.5” and extends toward higher temperatures probably as a con...
متن کاملHeat Capacity and Thermodynamic Functions of Ni36Nb24Zr40 Glassy Alloy
The heat capacity of a Ni36Nb24Zr40 glassy alloy was measured by adiabatic calorimetry from 13 to 300K. The smoothed values of molar heat capacity were calculated from the data using a least-squares method. The standard enthalpy, entropy, and Gibbs energy were calculated from the smoothed heat capacity values. Assuming Hð0Þ 1⁄4 0 and Sð0Þ 1⁄4 0 at 0K, the heat capacity, enthalpy, entropy, and G...
متن کاملLow-Temperature Heat Capacities and Thermodynamic Functions of Some Palladium and Platinum Group Cha1cogenides
Heat capacities of platinum disulfide, platinum ditelluride, and palladium ditelluride were measured in the range 5° to 350 K. They show the normal sigmoidal temperature dependence with no evidence of transitions or other anomalies. The derived heat capacity equations were integrated. Values of Cp , So Soo, HO-Hoo, and -(FO-HoO)/T are tabulated for selected temperatures. At 298.15°K the entropi...
متن کاملLow temperature heat capacities and thermodynamic functions described by Debye–Einstein integrals
Abstract Thermodynamic data of various crystalline solids are assessed from low temperature heat capacity measurements, i.e., from almost absolute zero to 300 K by means of semi-empirical models. Previous studies frequently present fit functions with a large amount of coefficients resulting in almost perfect agreement with experimental data. It is, however, pointed out in this work that special...
متن کاملLow-temperature excess heat capacity in fresnoite glass and crystal
The effect of thermal annealing on low-temperature excess heat capacity was investigated in fresnoite (Ba2TiSi2O8) glass. The amplitudes of the excess heat capacity decreased, and their positions shifted to a higher temperature by relaxation or crystallization. In particular, we revealed that the change in the excess heat capacity during transition from the glassy state to the crystalline state...
