Studies on the Synthesis and the Structure of Ferric Aluminum Magnesium Hydrotalcite-like Compounds
摘要:
The particles of ferric aluminum magnesium hydrotalcite-like compounds (Fe-Al-Mg_HTlc) were synthesized by co-precipitation method. It was found that when n(Fe)/n(Al+Mg+Fe)<0.30 and n(Al)/n(Al+Mg+Fe)<0.30, pure HTlc can be formed; when the molar ratio of Al/(Fe+Al+Mg)>0.30, Al(OH)3 will emerge; when the molar ratio of Fe/(Fe+Al+Mg)>0.30, the amorphous composition will appear. Hence Fe3+ and Al3+ have no concentration superposition effect on the crystal structure of the samples.
