Реферат: The structure of oxides obtained by the calcination of layered Mg–Al and Ni–Al (Mg/Al = Ni/Al = 2 : 1) double hydroxides with the structure of hydrotalcite. It is demonstrated that the formation mechanisms for the oxides are different: the Mg–Al oxide retains the original cation ratio, whereas the structure of the oxide formed represents a kind of layered defective spinel. Calcining the Ni–Al hydroxide results in the fact that the majority of Al3+ ions reaches the surface of the oxide particles, thereby forming aluminum hydroxide with retaining the nickel oxide phase in the course of hydration. It is established that, depending on the number of aluminum atoms in the bulk of the particles there are different structures of oxides formed, those determine the oxide ability either of restoring the layered oxide structure in the case of Mg–Al hydrotalcite, or saving the structure Ni–Al oxide in the course of hydration.
