A novel solvent free method for anhydrous MgCl2 from its hexahydrate is proposed, where in MgCl2?6H2O is dehydrated at 200 oC and ammoniated with NH3¬ directly to form MgCl2?6NH3 (HEX). This hexaammoniate complex is further calcined at 300 oC to obtain anhydrous MgCl2. A new fluidized dehydration of feed stock in a porous bed reactor yields a macro porous MgCl2-?nH2¬O (n
