Heat 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 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...

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...
15 صفحه اولThermodynamics of iron sulfides I . Heat capacity and thermodynamic properties of FesS 10
Measurements of the heat capacity of Fe9S a0 over the temperature range 5 K to 740 K reveal a first-order structural transition at 495 K and t~vo higher-order transitions with maxima at 534 K and 591 K. The last two are of coupled magnetic and structural origin. The structural changes giving rise to the heat-capacity effects are identified, and the magnetic properties are interpreted in terms o...
متن کاملSize-dependence of the heat capacity and thermodynamic properties of hematite (α-Fe2O3)
0021-9614/$ see front matter 2010 Elsevier Ltd. A doi:10.1016/j.jct.2010.04.009 * Corresponding author. Tel.: +1 801 422 2093; fax E-mail addresses: [email protected], Bri (B.F. Woodfield). The heat capacity of a 13 nm hematite (a-Fe2O3) sample was measured from T = (1.5 to 350) K using a combination of semi-adiabatic and adiabatic calorimetry. The heat capacity was higher than that of th...
