MTDATA – Phase Diagram Software from the National Physical Laboratory









Process Modelling at NPL

Johnson Matthey, working with NPL, have developed a general model using MTDATA for studying and predicting the distribution of elements in the high temperature processing of precious metals. The use of MTDATA provides a rigorous and reliable way to determine the partitioning of elements between phases. Now with the addition of process specific modelling this becomes an even move powerful tool.

For a number of years scientists at Johnson Matthey Technology Centre, in collaboration with Anglo American Platinum, have used MTDATA and thermodynamic databases from the National Physical Laboratory in order to gain a more fundamental understanding of key production processes. However recently it has become possible to use MTDATA, in this new and exciting way.
