It is widely recognised that phase diagram and thermochemical data are essential to answer many
practical questions that arise in the development of materials and their processing. The CALPHAD
method, a computer assisted calculation method, which offers a cost-effective and efficient
alternative to conventional methods to obtain much needed phase diagram and thermochemical
information in multicomponent systems. It is a combinatorial approach involving carefully selected
experimental data, results from theoretical estimation techniques and Gibbs energy models. Result
of such an exercise is a set of internally consistent Gibbs energy functions that describes the material
system. Powerful computer programs in combination with reliable Gibbs energy functions stored in
databases allow calculation of phase diagrams and thermochemical properties that suits one’s need.
Principles and advantages of the CALPHAD method are presented. Its application to ceramic systems
will be illustrated using examples from our on-going research.
