ABSTRACTAluminum lithium hydroxide carbonate hydrate, also known as Al-Li double hydroxide or Al-Li hydrotalcite-like compound [Al2Li(OH)6]2CO3•nH2O, was prepared from basic aluminum sulfate. This compound was prepared by precipitation in homogeneous solution of an aluminum bisulfite solution. A sodium aluminate aqueous solution was prepared by dissolving basic aluminum sulfate in 1M sodium hydroxide. The Al-Li double hydroxide was obtained after addition of lithium carbonate satured solution to the sodium aluminate solution, at 60 °C. The synthesized powder was characterized by thermal analysis (TG, DTG and DTA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). By this method crystalline Li-Al hydrotalcite like compound with composition near to Al4Li2(OH)12CO3 •3H2O was obtained.

The nature of the complex that had been formed by precipitating aluminum hydroxide between interlayer spaces of montmorillonite in the presence of anions Cl and SO4 was examined by chemical, X-ray, thermal, and infrared absorption methods. Results indicated that the complex was a hydroxy aluminum sulfate–montmorillonite with the structural formula: Al0.02(H2O)3[Al(OH)2.53(SO4)0.18] + silicate layer of montmorillonite [O10(OH)2 basis]. The atomic ratio, Al:OH:SO4, of the interlayer material was 1:2.53:0.18, which was similar to the ratio 1:2.5:0.25 of "basaluminite." X-ray data showed that the complex had spacings of 19.7, 21.9, and 24.4 A, under an extremely dry condition, moist condition, and on solvation with glycerol, respectively. During the heat treatments between 100 and 200 C, the d001 spacing was sharply reduced to 16 A and the newly developed phase persisted over a wide range of temperature from 200 to 600 C. This phase was considered as an interstratified structure consisting of a 14.3-A unit (chloritelike structure) and a 17.7-A unit (dehydrated basaluminite + silicate layer of montmorillonite). Although the d001 spacing observed for the unheated material was larger than that expected for the amount of aluminum precipitated in the montmorillonite, it was interpreted in terms of voluminous Al13O40 polyhedra that were described previously as basic structural units of a basic aluminum sulfate.
