摘      要：Shape apprearance and crystallite characterization of magnesium hydroxide at different hydrothermal temperatures have been investigated by SEM, XRD and DSC methods. The grain size, cell parameter and lattice distortion rate of powders under each condition were obtained. The results show that the grains had grown up, especially along the (001) surface as the hydrothermal temperature was raised, accompanying the shrinkage of lattice and the descending of distortion rate. These could be relate to the re crystallization of Mg(OH)2, as well as the thermal diffusion of OH-with lower charges, resulting in good dispersion, high thermal decomposition temperature and enthalpy of Mg(OH)2. Moreover, it is helpful for the increase of the retardant behavior of Mg(OH)2.
