Abstract
A series of M-Zn-Al (M = Mg, Cu) double hydroxide phases with carbonate anion have been prepared by coprecipitation at 333 K, from corresponding nitrate solution and sodium carbonate aqueous solution at pH 10. It seems that reactivity of aluminum ions into the host layer depends on the identity of coexistent divalent cations (magnesium or copper) and the thermal properties of this layer at relatively high temperatures also depends on the nature of divalent cations.
