Decarbonation Behavior of Mg-Al-CO3 Hydrotalcite-like Compounds during Heat Treatment
TL;DR: In this article, the authors demonstrate that when HTlcs having the maximum A1 content, AU(A1 + Mg) = 0.33, are heated to 5000C, 20-30% of the carbonates remain.

Chapter 13.1 Layered Double Hydroxides
TL;DR: The layered double hydroxides (LDH) have many physical and chemical properties that are surprisingly similar to those of clay minerals, such as variable layer charge density, ion-exchange properties, reactive interlayer space, swelling in water, and rheological and colloidal properties.

Physico-chemical properties of synthetic hydrotalcites in relation to composition
TL;DR: Ahstraet et al. as discussed by the authors used coprecipitation followed by hydrothermal treatment between 150 ~ and 250~C. Based on the structural formula [Mgl_xAlx(OH)~lX+l(COz)x/2 �9 mH20] x-, pure solid solutions were formed in the range Al/(Al + Mg) = 0.2 to 0.33, where m = (1 - 3x/ 2).
