National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Low-Temperature Heat Capacities and Enthalpy of Formation of Aluminum Sulfide (Al 2S3).

PB263564

Publication Date	1976
Personal Author	Ko, H. C.; Stuve, J. M.; Brown, R. R.
Page Count	15
Abstract	Calorimetric determinations of low-temperature heat capacities and the standard enthalpy of formation were made for aluminum sulfide, Al2S3. The standard entropy (So), enthalpy of formation (delta Gfo), and calculated Gibbs energy of formation (delta Gfo) at 298.15 K are 27.93 + or - 0.05 cal/deg-mole, -155.6 + or - .9 kcal/mole, and -153.0 + or - 1.0 kcal/mole, respectively.
