Effect of Compaction on the Kinetics of Thermal Dehydroxylation of Fire Clay

Department of Chemical Technology, University of Calcutta. 92, A P C Road, Calcutta-700 009 Manuscript received 15 June 1992, accepted 9 March 1993 Kinetics of thermal dehydroxylation of fire clay which is mainly disordered kaolinite, have been studied as a function of compaction of the loose aggregates. Kinetic parameters have been correlated with the pressure of pelletisation and also the disorderness inherent in the crystal structure
