Data for the Elements
The SGTE Unary Database is developed
maintained by SGTE, a consortium of centres engaged in the development
of thermodynamic databanks for inorganic and metallurgical systems and
their application to practical problems.
The SGTE Unary Database
contains data for around 78 elements in a form appropriate for phase
diagram modelling. Assessed data are provided for stable and metastable
phases for each element from 298.15 K, or in some cases 200 K. In some
cases, additional terms are included to describe the pressure or
magnetic contributions to the Gibbs energy. The data have been
published in a paper by Alan Dinsdale (NPL).

Dinsdale AT, CALPHAD, 15(4), 1991, pp. 317-425.
The data have been modified continuously since
this publication. The latest version of the UNARY database is version
4.4. A publication reflecting the latest version of the database is in preparation.
The data can also be viewed by following this link which displays a list
of the current recommended elements transition data.
Thermodynamic properties derived from these data
are tabulated in "Binary Alloy Phase Diagrams" (ASM International) and
in "CRC Handbook of Chemistry and Physics".
