Data 2004 2004-11-19 Enthalpy of Fusion of Bismuth: A Certified Reference Material for Differential Scanning Calorimetry An adiabatic calorimeter was used to measure the enthalpy of fusion of a sample of high-purity bismuth. The new value of the enthalpy of fusion was determined to be Hfus = (53.146 +/- 0.082) J.g-1, where the uncertainty corresponded to a 95% confidence interval. The temperature of fusion of this sample was found not to differ with previous accurate determinations within the accuracy of the fusion-temperature determination made in the present study. A comparison with some other enthalpy of fusion determinations is made. enthalpy of fusion bismuth adiabatic calorimeter 49 1364-1367 1 bismuth Bi 1 Commercial source 1 99.999 5 Stated by supplier 2 None used 1 1 Principal objective of the work SJR TRC 10/22/2004 1 Molar enthalpy of transition or fusion, kJ/mol Adiabatic calorimetry Crystal Direct value, X 1 Author Propagation of evaluated standard uncertainties 95 Crystal Liquid Gas 1 11106.47127548 5 1 17.13639116 1 1 Principal objective of the work JCE JCE 11/19/2004 1 Triple point temperature, K Adiabatic calorimetry Crystal Direct value, X 1 Author Propagation of evaluated standard uncertainties 95 Crystal Liquid Gas 1 544.556 6 1 .005
