Evidence for two stage mullite formation during thermal decomposition of kaolinite
Abstract Structural changes on heat treatment of English kaolinite have been studied by a standard X-ray technique. Changes in the lattice parameters, strain values, and crystal sizes of mullite and cristobalite have been calculated using a computer based Rietveld program. The results show two separate stages of mullite formation during the reaction of kaolinite. Changes in the composition of mullite during the course of its formation are discussed.
