Databases available for use with MTDATA

A range of databases of fundamental thermochemical data, covering a wide variety of system types, are offered for use with MTDATA. These databases have been built up by experts over many years, chiefly through the critical assessment of primary experimental data. The databases are under continuous development and expansion and the standard annual lease conditions allow for regular updates.

In addition to the databases listed below, users can create and manage private databases geared to their own applications. Customised databases can also be designed to cater for specific requirements.

The databases available for use with MTDATA are suited to a wide range of applications.

To download the databases described here please follow the Downloads link here or at the side of this page.


SGTE Databases

SGTE LogoNPL is a member of SGTE, which is a consortium of centres engaged in the development of thermodynamic databases for inorganic and metallurgical systems and their application to practical problems.

The databases are compiled by a panel of experts by critically assessing data for pure substances and solutions of all types: aqueous, gases, alloys, mattes, slags, salts, oxides and semiconductor systems. The experts meet on a regular basis to ensure the continuous development of the databases. There are three SGTE databases currently available.


Other Databases

Some other Databases which can be supplied for use with MTDATA are:

For a complete list of databases and their current versions please see the Databases section on the current releases page.


Databases under development

NPL is developing other databases for use with MTDATA. The following are expected to be released in 2008:

  • MTCEMENT - For the modelling of ordinary Portland cement (OPC) based materials and their behaviour in contact with various atmospheric and aqueous environments.
  • MTOXVISC - For the prediction of the viscosity of slags and other oxide liquids as a function of temperature and composition. This is based on the MTOX Oxide Database and makes use of the calculated amounts of oxide species in order to evaluate the viscosity.
  • MTOXTRACE - An extension of the MTOX Oxide Database covering dilute solutions of a number of additional cations and anions (eg carbonate, sulphate, hydroxide).
  • MTTHERM - a specific database for use in the teaching of thermodynamics as part of an undergraduate teaching course.
  • MTAPPLIC - a database developed for calculations associated with specific industrial applications highlighted in more advanced thermodynamic courses.
