Mullite is an important phase in several ceramic articles such as in triaxial composition, but the formation of mullite during processing is limited to a certain extent due to thermodynamic reasons. The invention, mullite formation during firing is catalyzed by a novel process that not only leads to in-situ formation of mullite in the ceramic systems but also enhances mullite content in the range of 2 to 4% more than the conventional processes. Additionally, the invention discloses a process which requires a lower temperature for the preparation of ceramic articles and therefore is a cost effective process.
