A survey is presented of the principles and practice of tailoring: sintering liquid composition and processing cycle to enable crystallisation of intergranular phases in silicon nitride and sialon ceramics, Critical features in sialon ceramics are the O/N balance in residual glasses and post-sintering heal-treatment temperatures to enable nucleation of either intermediate phases at constant composition or oxide phases with re-partitioning of non stoichiometric components in beta' or alpha' solid solutions. Crystallisation of disilicate phases in non sialon compositions exemplifies a problem in control of polymorphs with differing atomic volumes. Crystallisation of intergranular phases has an influence mainly on high-temperature mechanical and environmental behaviour of these ceramics.
