Contributions to the Data on Theoretical Metallurgy: [Part] 9. The Entropies of Inorganic Substances. Revision (1940) of Data and Methods of Calculation

Description: From Introduction: "This bulletin originally was planned as a second revision of the first member of this series, the first revision (249) having appeared in 1936; however, because of requests for the explanatory, section of the first bulletin from those teaching thermodynamics, it was decided to combine the information in the first bulletin and its revision with the data that have appeared since 1935 and to repeat the explanatory material in somewhat more detail. The purpose of this bulletin is therefore to give the available values of the entropies at 298.1 degrees K. of the elements and inorganic compounds, together with enough explanation of the methods employed in calculating entropies to make the results comprehensible."

Contributions to the Data on Theoretical Metallurgy: [Part] 10. High-temperature Heat-Content, Heat-Capacity, and Entropy Data for Inorganic Compounds

Description: From Introduction: "This work is both a revision and an elaboration of Bureau of Mines Bulletin 371, which was published in 1934 and included data available to October 1933. This bulletin purposes to collect and correlate all available high-temperature heat-content and specific-heat data for inorganic substances and to formulate tables and algebraic expressions for their representation. It is expected also that this bulletin will have value to those teaching courses in metallurgical and chemical thermodynamics."

Development and Use of Certain Flotation Reagents

Description: From Forward: "When the experiments described in this bulletin were begun many of the reagents were available only in trial quantities. Some of them are now available in commercial quantities and are of different compositions from those that were available for experimental work. It was not possible to determine the exact chemical composition of some of the reagents."
