Different methods for the preparation of high purity NaAlCl.sub.4 are disclosed. The methods includes charging a feed having an intimate mixture of aluminum chloride, sodium chloride, and aluminum metal, to a reactor at an initial temperature less than about 80 C., carrying out a solid state reaction to form a solid NaAlCl.sub.4 at an intermediate temperature less than about 145 C., melting the formed solid NaAlCl.sub.4 at an elevated temperature greater than about 150 C. to produce molten phase NaAlCl.sub.4, holding the reactor at a raised temperature greater than about 165 C. to substantially complete formation of colorless NaAlCl.sub.4 and filtering the reactor contents at a final temperature greater than about 165 C.

A method for preparing a crystallized solid material of formula LiCl.2Al(OH).sub.3.nH.sub.2O with n being comprised between 0.01 and 10, includes mixing in an aqueous medium, at least one source of alumina and at least one source of lithium in order to obtain a suspension, filtering the resulting suspension obtained for obtaining a slurry, followed by drying the obtained slurry and shaping the dried slurry after the drying to obtain a shaped solid material. The shaping is carried out in absence of a binder followed by drying and a hydrothermal treatment to obtain the shaped crystallized solid material of formula LiCl.2Al(OH).sub.3.nH.sub.2O. A method for extracting lithium from saline solutions uses the thereby prepared material.
