Report issued by the Bureau of Mines over studies on the thermodynamics of sulphur. As stated in the introduction, "the present bulletin has as its primary purpose the correlation of the thermodynamic properties of elementary sulphur and its inorganic compounds and the presentation, after careful consideration of all available information, of a self-consistent system of thermodynamic relationships for these substances" (p. 1). This report includes tables.

From introduction: "The present work reviews the available high-temperature thermal data on inorganic compounds and gives representative specific-heat equations valid at high temperatures for use in thermodynamic calculations."

From Introduction: "Examples of the use of the derived heat-of-fusion values in the application of thermodynamics to problems concerning metallurgical practice are not given here, but the reader is referred to the textbook of Lewis and Randall (454), in which the methods and types of calculations are adequately portrayed, and to the papers of Maier (469, 470, 471), in which the application of thermodynamic methods to various problems of metallurgical interest has been illustrated and discussed."

From Introduction: "Moreover, a critical study of the existing vapor-pressure data made by the author (98) furnishes entropy of vaporization results suitable for obtaining approximate values of the entropies of a number of gases from the entropies of the solids or liquids. Consequently, it appears worth while at the present time to supplement the former publication, giving the new values now obtainable and making such revision in the older values as the data warrant."

From Introduction: "It is the purpose of this present work (1) to apply the previously compiled entropy values and specific-heat equations to vapor-pressure and other pertinent data in obtaining heat and free energy of vaporization equations for inorganic substances valid up to the normal boiling or sublimation points (760 mm pressure), (2) to supplement wherever possible the data on heats and entropies of transformations and fusions, (3) to supplement wherever possible the data on heats and entropies of gases, and (4) to supply tables of vapor pressures for inorganic substances at various temperatures up to and including the boiling or sublimation point."

From Introduction: "This publication proposes to assemble existing thermodynamic data for carbonates and to correlate so far as possible the results of decomposition-pressure determinations with the calorimetrically determined heats of formation and entropy values on the one hand and with solubility and standard electrode-potential data on the other."

From Introduction: "The present work is an attempt to collect all the available data referring to one important thermodynamic property and to supply sufficient discussion to make the results readily usable by metallurgists. In the study of chemical or metallurgical reactions two factors have predominant importance-the free energy of reaction and the speed of reaction. The subject of this publication is so closely allied to the former that may be well to consider briefly some of the uses to which free-energy data may be put."

From Introduction: "The present paper collects and discusses thermodynamic data relating to metal carbides and nitrides, with the view of obtaining usable heat and free energy of formation relationships."
