Abstract

Abstract

Carbonate pillared Mg-Al-In hydrotalcites were synthesized by coprecipitation. Various preparative factors such as precipitation method, operation temperature, pH value, aging time and n (Mg): n (Al): n (In) molar ratio, which affect the purity and crystal form of Mg-Al-In hydrotalcite-like compound were studied. The results of product characterization by XRD and IR methods show that high supersaturation coprecipitation at constant pH, handing precepitation temperature and aging temperature at 65℃, washing temperature at room temperature, pH ranging from 10 to 11.5, aging for 8 h and n (In³⁺)/n (M³⁺) molar ratio ranging from 0.1 to 0.8, may give rise to high purity and better crystal form of Mg-Al-In hydrotalcite-like compounds.
