Article Preview

Synthetic manganeous Layered Double Hydroxides of the Hydrotalcite- and Shigaite- type were prepared by the coprecipitation method. The thermal behaviour of two compounds, [Mn6Al3(OH)18] [(SO4)2Na·12H2O] and [Mn6Al3(OH)18] [Cl·4H2O] was investigated by several experimental techniques. Thermal analysis and in-situ X-ray diffractometry show several dehydration stages of the synthesis products in the temperature range of 25 < T < 170°C followed by decomposition at temperatures above 200°C.
