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

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

versions please see the Databases section on the current
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.
