Materials Chemistry Committee - mission

Scope Statement

The committee is interested in all aspects of the phase equilibria, including metastable equilibria and kinetics, in all classes of engineering materials and covering both fundamental and applied topics. To this aim it provides a means by which critical assessment and experimental work carried out in various organisations and institutions in the UK can be discussed and hence undue overlap of experimental studies avoided. The committee will encourage international co-operation on phase diagram knowledge. It recognises the vital role that reliable information on phase diagrams and the rates of approach to equilibrium play in underpinning many spheres of materials science and technology. These include extraction, refining, processing and use of materials in traditional large scale industries as well as emerging applications and industries.


The committee will encourage all aspects of experimental and theoretical work relating to phase equilibria in materials systems ranging from direct studies of phase diagrams and the determination of thermodynamic mixing parameters to the thermodynamic modelling of phases and ab initio calculations of phase stability and microstructure. The committee is also interested in the chemical properties of materials and their syntheses.


The committee will also seek to support academic institutions in their role in the teaching of thermodynamics and phase equilibria and to ensure that materials scientists in industry have adequate training in this area of fundamental importance.



A central role of the committee’s activities is to ensure that UK industry and academia are provided with access to the most up-to-date, accurate and reliable information and data relating to phase equilibria and the kinetics of reactions and transformations.This will be achieved through encouraging publications in the journals of the Institute, such as Materials World and Materials Science and Technology, through the committee’s web pages and by organising seminars and workshops. The committee’s membership will aim to be a balance between providers and users of such information and will benefit from the continued strong industrial input it has enjoyed since its formation. The committee will provide a forum to identify industrial needs, a discussion group between specialists and a focus within the Institute of Materials for active international collaboration on the provision of assessed data, on modelling, and on theoretical and computational aspects of phase equilibria in materials.



The committee will foster strong working relationships with UK industry and will build on the strong international links with similar organisations and groups abroad. The committee will act as the Institute’s link with APDIC*.Liaison with other Institute committees such as the Structure and Properties of Materials, High Temperature Materials and other committees representing the minerals sector is a high priority. Joint activities are anticipated on biomaterials, electronic materials, environmental aspects of materials, minerals processing and pharmaceutical products. The committee will develop links with similar groups in other professional bodies such as the RSC, IoP, SCI and IEEE.
