Process for the thermal decomposition of aluminum chloride hexahydrate into anhydrous Al2O3, comprising predrying and then decomposition in a fluidization reactor, the said fluidization being ensured by recycled gaseous HCl, and finally heating at the temperature necessary to obtain the desired crystallization state, namely anhydrous Al2 O3, the said pre-drying being carried out by the gases coming from this final heating. |
