摘要: Magnesium-aluminum-iron layered hydroxides with hydrotalcite-like structure have been synthesized, and their chemical composition crystal lattice parameters elucidated. Thermal decomposition of the iron-containing has studied by X-ray diffraction, thermogravimetry, IR spectroscopy; starts loss interlayer water, followed dehydroxylation metal hydroxide layers anions at higher temperature. Onset both stages shifted to lower temperature increasing iron fraction in sample. restore after annealing subsequent rehydration.
