MTDATA
Materials problems
faced by industry tend to be
complex in nature, involving interactions between different
materials, including alloys, ceramics, glasses, cements and minerals,
as well as melts, aqueous solutions and gases. The number of process
variables is often quite large, making feasibility studies and
experimental optimisation expensive.
The Thermodynamics and
Process Modelling Group, in
the Materials Centre
at the National Physical Laboratory,
has long been involved in the use of thermodynamic data for inorganic
and metallurgical systems
and in the solution of practical problems for a wide range of areas of
interest to industry such as:
|
- Alloy
development
- Extraction
and recycling
- Energy
conversion
- Joining
- Materials
processing
- Corrosion and
deposition
- Chemistry in
technology
- Electronic
and magnetic materials
- Environmental
control
- Polymers
|
One result of this
long term interest has been the
development of MTDATA,
a software/data package, developed at NPL, which uses critically
assessed thermodynamic data in order to
calculate phase equilibria and thermodynamic properties for
multicomponent multiphase systems appropriate to problem of immediate
interest.
A number of high
quality thermodynamic data for an
extensive range of
material types are available for use
with MTDATA. The types of materials covered include light
alloys, steels, ceramics,
glasses, slags, mattes,
salts, polymers, aqueous
solutions and gases. MTDATA, in
combination with these data, can be used to predict the chemical
species and phases likely to form at equilibrium in the types of system
of greatest industrial interest - those containing large numbers of
chemical elements - and so provide a valuable guide to the solution of
many industrial problems. Organisations can lease these databases and MTDATA
for in-house use or ask for calculations to be done at NPL. For further
information about the
services offered at NPL please click here.
NPL is involved in a
wide range of scientific
research concerned with
thermodynamic data ranging from the development of data for solders and
complex oxides systems to the investigation of the application of ab-initio
techniques for the prediction of thermodynamic data. For more

NPL is very active
within SGTE.
Alan Dinsdale is chairman and president of SGTE and also the manager of
the SGTE Solution Database. He has maintained the database containing
standard reference data for the elements on behalf of SGTE. SGTE
databases can obtained for use with MTDATA.
NPL also plays an
active role within the Institute
of Materials through
the Materials
Chemistry Committee and, in a wide sense, through APDIC.
