Discrimination between synthetic MgAl double hydroxides and related carbonate phases

Pure mixed MgAl double hydroxides were utilized for the preparation of the corresponding MgAl hydroxycarbonates. Three different modes of carbonation were adopted: CO 2 was bubbled through MgAl double hydroxides or these compounds underwent exchange with NaHCO 3 or Na 2CO 3 in aqueous solution. T...

Description
Summary:Pure mixed MgAl double hydroxides were utilized for the preparation of the corresponding MgAl hydroxycarbonates. Three different modes of carbonation were adopted: CO 2 was bubbled through MgAl double hydroxides or these compounds underwent exchange with NaHCO 3 or Na 2CO 3 in aqueous solution. The resulting carbonated phases were investigated by X-ray, DTA, TG, and analysed chemically, and the results compared with those of mixed MgAl double hydroxides.
