Thermodynamic Properties of 65 Elements: Their Oxides, Halides, Carbides and Nitrides

Description: From Introduction: "This Bureau of Mines bulletin was prepared to compile in readily usable form the heat content, heat-of-formation, and free-energy-of-formation data for 65 common elements and their respective oxides, halides, carbides, and nitrides. The bulletin was prepared to encourage the application of thermodynamics in the metallurgical field; consequently, the values have been presented in a simple, readily usable form and several examples of their applications have been shown."
