Synthesis and Characterization of Magnetic Nanometer-sized Mg-Al Hydrotalcites
Abstract:
The magnetic compounds were prepared from Mg-Al hydrotalcites by the method of co-precipitation, and the magnetic Mg-Al hydrotalcite particles sized in 20~50 nm were synthesized to give assembled layered magnetic materials. The influences of Mg/Fe(Ⅱ) molar ratio on the structure of hydrotalcites and its magnetic property were investigated by XRD, TEM, vibrating-sample magnetometer(VSM), TG-DTA and FT-IR. The results showed that the addition of magnetic substrates didn't change the typical characters of layered-structure and mass loss on heating. And the specific saturation magnetization of products increased linearly with the content of magnetic particles.
