Enthalpy of Fusion of Bismuth: A Certified Reference Material for Differential Scanning Calorimetry

Published

Author(s)

Donald G. Archer

Abstract

An adiabatic calorimeter was used to measure the enthalpy of fusion of a sample of high-purity bismuth. The new value of the entalpy of fusion was determined to be delta^fusH=(53.146 plus or minus 0.082) J multiplied g negative 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 comparision with some other enthalpy of fusion determinations is made.
