Abstract
The heat capacity of natural zinc carbonate (smithsonite, ZnCO3) has been measured by the method of low-temperature adiabatic calorimetry over the temperature range of (4.4 to 320)K. Its thermodynamic functions have been calculated based on the experimental data on the heat capacity. The standard values of the heat capacity and entropy for smithsonite are as follows: Cp,m=80.36±0.09J·mol−1·K−1, Sm=81.28±0.09J·mol−1·K−1.
