    • Description:
      "The thermodynamic properties of two manganese silicates pyroxmangite and fowlerite (zincian rhodonite) were experimentally determined by the Bureau of Mines. The standard enthalpies of formation were determined by hydrofluoric acid (hf) solution calorimetry, the low- temperature heat capacities by adiabatic calorimetry, and the high- temperature heat capacities by differential scanning calorimetry over the range 322 to 1,372 k. These experimentally determined values were combined with data from the literature to calculate the Gibbs energies and equillibrium constants of formation over the temperature range of the measurements. Standard enthalpies, Gibbs energies, and equillibrium constants of formation are given as a function of temperature from both the elements and the constituent oxides." - NIOSHTIC-2
