The possibility of synthesizing hydrotalcite (HT) as a single phase using calcined dolomite as a magnesium and alkali source was examined. Calcined dolomite consisted of a mixture of CaO and Mg. The effects of initial Mg/Al molar ratio, temperature, and time on the formation of HT were investigated. HT was gradually found to be regenerated by the reactions of the dissolved Mg and Al species.
