The chlorination reaction of Li_2CO_3 with NH_4Cl has been studied in detail by a series of thermal analysis methods. When NH_4Cl/Li_2CO_3 mole ratio equals 4, Li_2CO_3 can be transformed into LiCl quantitatively in a stream of Ar gas flow. All residual NH_4Cl is decomposed completely at 400 ℃ and carried away from the reaction cell by Ar gas.Analysis by X-Ray diffraction and Ion Chromatography show that there are almost no NH_4Cl remained in The LiCl product. It is interested that the chlorination reaction can be applied to the determinations of phase diagram by thermal analysis method and the preparation of Al-Li alloy by electrolysis in molten salt.
