제목 The Study on the Physical Properties of Crystal Structure Hydrotalcite formed at High Temperature
초록 The synthetic Mg-Al LDHs (Hydrotalcite) with different Mg/Al molar ratios were co-precipitated in the low temperature but this study has carried out the hydrothermal treatment in autoclaves at 160-180 ℃ for 48 hour. In general, synthesized hydrotalcites from the low temperature by co-precipitation method showed the agglomeration of small crystals and difficult to the control of particle sizes but synthesized hydrotalcites at the high temperature with longer time were indicated an increasing growth of crystallites as well as an improvement of the crystallinity. The obtained samples were characterized using powder X-ray diffraction and scanning electron microscopy for crystallinity.
