The Zn-Al LDHs、Mg-Al LDHs and Co-Al LDHs powders were prepared with low-super-saturation-co-precipitation method.The presented samples were characterized in detail by X-ray diffraction（XRD）,infrared spectroscopy（FT-IR） and thermo-gravimetric differential thermal analysis（TG-DTA）.The results showed that the above series of hydrotalcite by low-super-saturation-co-precipitation possessed high crystallinity,overall plan,good layered structure and thermal properties.
