Kinetic study of talc dehydroxylation by controlled rate thermal analysis
Kaouther Belgacem, M.Trabelsi-Ayadi
Controlled Rate Thermal Analysis (CRTA) has been used under both low water vapour pressure (10-3mbar) and lowtransformation rate (5.33×10-6s-1) to investigate the dehydroxylation kinetic of talc sample fromLuzenac. The decomposition is first controlled by diffusion process in three dimensions (D4) up to ï¡ = 0.70 then for 0.7 < á < 1, it becomes governed by first order mechanism(F1). The apparent activation energy determined experimentally was found constant at 417 20 kJ.mol-1.
