Thermodynamic data of chemical elements

Since 1974, the Thermodata association has been managing a bank of selected and critically reviewed digital data covering the fields of metallurgy and dry (non-aqueous) inorganic chemistry.

It has three functions:

• maintains and distributes the thermochemical database;

• acts as a consultant and design office for its customers, guaranteeing confidentiality;

• participates within a group of experts (GIE SGTE: Scientific Group Thermodata Europe) in the effort to maintain and enhance data holdings.

The values in this file have been extracted from the database and are presented in tabular form.

In this article, element properties are presented as a function of temperature expressed in kelvins and for a standard pressure of 1 atm (101,325 Pa). It should be noted, however, that the standard pressure can be fixed at 10 ⁵ Pa. In this case, only the S° values of the gaseous species will be affected in this sense: S° (g, p° = 10 ⁵ Pa) J · K ^–1 ·mol ^–1 = S° (g, p° = 101 325 Pa) J · K ^–1 ·mol ^– 1 + 0.109
